Ƙarfe Stabilizers Sabulun Ƙarfe: Gyara Ciwon Ciki na Samar da PVC & Farashin Slash

DominPVC masana'antun, Daidaita ingancin samarwa, ingancin samfurin, da sarrafa farashi sau da yawa yana jin kamar tafiya mai tsauri-musamman idan ya zo ga masu daidaitawa. Yayin da masu ƙarfin ƙarfe masu guba (misali, gishirin gubar) ba su da arha, suna haɗarin hani na tsari da lahani masu inganci. Zaɓuɓɓukan ƙima kamar organotin suna aiki da kyau amma karya banki. Shigakarfe sabulu stabilizers- tsaka-tsakin tsaka-tsakin da ke magance manyan ciwon kai na samarwa kuma yana kiyaye farashi.

An samo shi daga fatty acids (misali, stearic acid) da karafa kamar calcium, zinc, barium, ko magnesium, waɗannan masu daidaitawa suna da m, yanayin yanayi, kuma an keɓance su zuwa wuraren zafi na PVC na yau da kullun. Bari mu nutse cikin yadda suke gyara matsalolin samarwa da rage farashi — tare da matakan aiki don masana'anta.

Sashe na 1: Masu Tsabtace Sabulun Ƙarfe Suna Warware Waɗannan Matsalolin Samar da Mahimmanci guda 5

Samar da PVC ya gaza lokacin da masu daidaitawa ba za su iya ci gaba da aiki da zafi ba, buƙatun dacewa, ko ƙa'idodin ƙa'ida. Sabulun ƙarfe yana magance waɗannan batutuwa gaba-gaba, tare da haɗakar ƙarfe daban-daban waɗanda ke niyya takamaiman wuraren zafi.

Matsala ta 1:"Mu PVC yellows ko fasa a lokacin high-zafi aiki"

Ragewar thermal (sama da 160 ° C) shine babban abokin gaba na PVC-musamman a cikin extrusion (bututu, bayanan martaba) ko calending (fatar wucin gadi, fina-finai). Na'urorin daidaitawa na ƙarfe-ƙarfe na gargajiya (misali, sabulun zinc mai tsafta) kan yi zafi sosai, yana haifar da “ƙona zinc” (tabo masu duhu) ko gatsewa.

Magani: Calcium-Zinc (Ca-Zn) Haɗin Sabulu
Ca-Zn karfe sabulusune ma'auni na zinariya don kwanciyar hankali na thermal ba tare da ƙananan karafa ba. Ga dalilin da ya sa suke aiki:

Calcium yana aiki a matsayin "matsayin zafi," yana rage jinkirin dehydrochlorination na PVC (tushen sanadin rawaya).

• Zinc yana lalata hydrochloric acid (HCl) mai cutarwa wanda aka saki yayin dumama.

• An haɗa su daidai, suna jure wa 180-210 ° C na minti 40 +-cikakke don PVC mai tsauri (bayanin bayanan taga) da PVC mai laushi (vinyl flooring).

Nasiha Mai Aiki:Don matakan zafi mai zafi (misali, extrusion bututun PVC), ƙara 0.5-1%calcium stearate+ 0.3-0.8%zinc stearate(jimlar 1-1.5% na nauyin resin PVC). Wannan yana bugun aikin gishirin gubar kuma yana guje wa guba.

Matsala ta 2:"PVC ɗinmu yana da ƙarancin kwarara - muna samun kumfa mai iska ko kauri mara daidaituwa"

PVC yana buƙatar gudana mai santsi yayin gyare-gyare ko sutura don guje wa lahani kamar filaye ko ma'aunin da bai dace ba. Masu daidaitawa masu arha (misali, sabulun magnesium na asali) galibi suna yin kauri, suna rushe aiki.

Magani: Barium-Zinc (Ba-Zn) Haɗin Sabulu
Ba-Zn irinsabulu ya yi fice wajen inganta narkewar ruwa saboda:

• Barium yana rage dankowar narkewa, yana barin PVC ya bazu a ko'ina a cikin gyare-gyare ko kalanda.

• Zinc yana haɓaka kwanciyar hankali na thermal, don haka ingantaccen kwarara ba ya zuwa da tsadar lalacewa.

Mafi kyawun Ga:Aikace-aikace masu laushi na PVC kamar risho mai sassauƙa, rufin kebul, ko fata na wucin gadi. Haɗin Ba-Zn (1-2% na nauyin guduro) yana yanke kumfa da kashi 30-40% idan aka kwatanta da sabulun magnesium.

Pro Hack:Mix tare da 0.2-0.5% polyethylene kakin zuma don haɓaka kwararar gaba-babu buƙatar gyare-gyaren kwarara mai tsada.

Matsala ta 3:"Za mu iya'Yi amfani da PVC da aka sake yin fa'ida saboda masu daidaitawa suna karo da filaye"

Yawancin masana'antu suna so su yi amfani da PVC da aka sake yin fa'ida (don rage farashin) amma suna gwagwarmaya tare da dacewa: resin resin sau da yawa yana ƙunshe da abubuwan da suka rage (misali, calcium carbonate) ko robobi waɗanda ke amsawa tare da masu daidaitawa, suna haifar da gajimare ko tsinkewa.

Magani: Magnesium-Zinc (Mg-Zn) Haɗin Sabulu
Sabulun ƙarfe na Mg-Zn sun dace sosai tare da PVC da aka sake yin fa'ida saboda:

• Magnesium yana ƙin amsawa tare da filler kamar CaCO₃ ko talc.

• Zinc yana hana sake lalata tsoffin sarƙoƙi na PVC.

Sakamako:Kuna iya haɗa 30-50% PVC da aka sake yin fa'ida cikin sabbin batches ba tare da asara mai inganci ba. Misali, mai yin bututu da ke amfani da sabulun Mg-Zn ya rage farashin guduro na budurwa da kashi 22% yayin saduwa da ma'aunin ƙarfin ASTM.

Matsala ta 4:"Kayan mu na waje na PVC yana fashe ko shuɗe a cikin watanni 6"

PVC da aka yi amfani da shi don bututun lambu, kayan daki na waje, ko siding yana buƙatar UV da juriya na yanayi. Madaidaitan masu daidaitawa suna rushewa a ƙarƙashin hasken rana, wanda ke haifar da tsufa da wuri.

Magani: Calcium-Zinc + Haɗin Sabulun Karfe Rare Duniya
Ƙara 0.3-0.6% lanthanum ko cerium stearate (sabulun ƙarfe mara nauyi) zuwa gaurayar Ca-Zn ku. Wadannan:

• Shake UV radiation kafin ya lalata kwayoyin PVC.

• Ƙara tsawon rayuwar waje daga watanni 6 zuwa shekaru 3+.

Nasara Farashin:Sabulun da ba kasafai ba ya kai ƙasa da ƙwararrun masu ɗaukar UV (misali, benzophenones) yayin isar da irin wannan aikin.

Matsala ta 5:"Masu siyan EU sun ƙi mu don alamun gubar/cadmium"

Dokokin duniya (REACH, RoHS, California Prop 65) sun hana karafa masu nauyi a cikin PVC. Canja zuwa organotin yana da tsada, amma sabulun ƙarfe yana ba da madadin dacewa.

Magani: Duk Haɗin Sabulun Karfe (Babu Ƙarfe Mai nauyi)

•Ka-Zn, Ba-Zn, kumaMg-Zn sabuluba su da gubar 100% / cadmium.

• Sun cika REACH Annex XVII da US CPSC-mahimmancin kasuwannin fitarwa.

Hujja:Wani mai kera fina-finai na PVC na kasar Sin ya canza daga gishirin gubar zuwa sabulun Ca-Zn kuma ya dawo da kasuwar EU a cikin watanni 3, yana haɓaka fitar da kayayyaki da kashi 18%.

Sashe na 2: Yadda Masu Gyaran Sabulun Karfe ke Yanke Kuɗi (Hanyoyin Aiki 3)

Stabilizers yawanci suna da kashi 1-3% na farashin samarwa na PVC-amma zaɓi mara kyau na iya ninka farashin ta hanyar sharar gida, sake yin aiki, ko tara. Sabulun ƙarfe yana haɓaka farashi ta hanyoyi guda uku:

1. Slash Raw Material Farashin (Har zuwa 30% Mai Rahusa Fiye da Organotin)

• Organotin stabilizers kudin $8-$12/kg; Sabulun karfe na Ca-Zn ya kai $4-$6/kg.

• Domin masana'anta da ke samar da tan 10,000 na PVC / shekara, canzawa zuwa Ca-Zn yana adana ~ $ 40,000- $ 60,000 kowace shekara.

• Tukwici: Yi amfani da sabulun ƙarfe "wanda aka riga aka haɗa" (masu kawowa suna haɗa Ca-Zn/Ba-Zn don ƙayyadaddun tsari na ku) don guje wa wuce gona da iri na masu daidaita sassa guda ɗaya.

2. Rage ƙima da 15-25%

Sabulun ƙarfe 'mafi kyawun yanayin zafi da daidaituwa yana nufin ƙarancin ƙarancin batches. Misali:

• Ma'aikatar bututun PVC ta amfani da sabulun Ba-Zn yanke tarkace daga 12% zuwa 7% (ajiye ~ $ 25,000 / shekara akan guduro).

• Mai yin shimfidar bene na vinyl ta amfani da sabulun Ca-Zn ya kawar da lahani na "rawaya baki", yana rage lokacin sake yin aiki da kashi 20%.

Yadda Ake Aunawa:Bi diddigin ƙimar juzu'i na wata 1 tare da mai daidaitawa na yanzu, sannan gwada haɗakar sabulun ƙarfe-mafi yawan masana'antu suna ganin haɓakawa cikin makonni 2.

3. Inganta Sashi (Amfani Kadan, Samun Ƙari)

Sabulun ƙarfe sun fi na'urorin daidaitawa na gargajiya inganci, don haka zaka iya amfani da ƙaramin adadi:

• Gishiri na gubar na buƙatar 2-3% na nauyin resin; Haɗin Ca-Zn yana buƙatar 1-1.5% kawai.

• Domin aikin 5,000-ton/shekara, wannan yana rage amfani da stabilizer da tan 5-7.5/shekara ($20,000-$37,500 cikin tanadi).

Hack Test Sashe:Fara da sabulun ƙarfe 1%, sannan ƙara da 0.2% increments har sai kun cimma ingantacciyar manufa (misali, babu rawaya bayan mintuna 30 a 190°C).

Sashe na 3: Yadda Ake Zaɓan Madaidaicin Sabulun Stabilizer (Jagora Mai Sauri)

Ba duk sabulun ƙarfe ba daidai suke ba-daidai da haɗuwa da nau'in PVC da tsari:

Tukwici Na Ƙarshe: Abokin Hulɗa Tare da Mai Bayar Ku don Haɗin Kai na Musamman

Babban kuskuren da masana'antu ke yi shine amfani da sabulun ƙarfe "mai girma ɗaya-daya". Tambayi mai samar da stabilizer don:

• Haɗin da aka keɓance da zafin sarrafa ku (misali, zinc mafi girma don extrusion 200°C).

• Takaddun yarda na ɓangare na uku (SGS/Intertek) don guje wa haɗari na tsari.

• Samfurin batches (50-100kg) don gwadawa kafin haɓakawa.

Matsakaicin sabulun ƙarfe ba kawai “zaɓi na tsakiya bane” - su ne mafita mai wayo ga masu kera PVC sun gaji da zabar tsakanin inganci, yarda, da farashi. Ta hanyar daidaita madaidaicin haɗakar da tsarin ku, za ku yanke sharar gida, ku guje wa tara, da kuma kiyaye tatsuniyoyi lafiya.

Shirya don gwada haɗakar sabulun ƙarfe? Ajiye sharhi tare da aikace-aikacen PVC ɗinku (misali, “m bututu extrusion”) kuma za mu raba abin da aka ba da shawarar!

Wannan shafin yana ba da takamaiman nau'ikan sabulun ƙarfe, hanyoyin aiki masu amfani, da bayanan ceton farashi don masu kera PVC. Idan kana buƙatar daidaita abun ciki don takamaiman aikace-aikacen PVC (kamar fata na wucin gadi ko bututu) ko ƙara ƙarin cikakkun bayanai na fasaha, jin daɗi don sanar da ni.
