Yiziphi I-Lead Stabilizers? Iyini ukusetshenziswa kwe-lead ku-PVC?

Izinza zokuhola, njengoba igama liphakamisa, ziwuhlobo lokuqiniswa olusetshenziswa ekukhiqizeni i-polyvinyl chloride (PVC) namanye ama-polymer we-vinyl. Lezi ziqinisi ziqukethe izinhlanganisela zokuhola futhi zengezwe ekwakhiweni kwe-PVC ukuvimbela noma ukunciphisa ukuwohloka kokushisa kwe-polymer ngesikhathi sokucubungula nokusebenzisa.Ama-stabilizer aholayo ku-PVCbezilokhu zisetshenziswa kabanzi embonini ye-PVC, kodwa ukusetshenziswa kwazo kwehlile kwezinye izifunda ngenxa yokukhathazeka kwemvelo nempilo okuhambisana nomthofu.

Amaphuzu abalulekile mayelanai-lead stabilizerszihlanganisa:

 

I-Stabilizing Mechanism:

Ama-Lead stabilizers asebenza ngokuvimbela ukuwohloka kokushisa kwe-PVC. Zenza i-acidic byproducts ingasebenzi ngesikhathi sokuwohloka kwe-PVC emazingeni okushisa aphakeme, ivimbele ukulahleka kobuqotho besakhiwo se-polymer.

 

Izicelo:

Iziqinisi zomthofu bezilokhu zisetshenziswa ngokwesiko ezinhlelweni ezahlukahlukene ze-PVC, kufaka phakathi amapayipi, ukuvala amakhebula, amaphrofayili, amashidi, nezinye izinto zokwakha.

 

Ukuqina Kokushisa:

Bahlinzeka ngokuqiniswa kokushisa okuphumelelayo, okuvumela i-PVC ukuthi icutshungulwe emazingeni okushisa aphezulu ngaphandle kokuwohloka okukhulu.

 

Ukuhambisana:

Ama-lead stabilizer aziwa ngokuhambisana kwawo ne-PVC kanye nekhono lawo lokugcina izakhiwo zemishini nezomzimba ze-polymer.

 

Ukugcinwa Kombala:

Banikela ekuzinzeni kombala wemikhiqizo ye-PVC, okusiza ukuvimbela ukuguquguquka okubangelwa ukuwohloka kokushisa.

 

Ukucatshangelwa Kokulawula:

Ukusetshenziswa kwezinzinzisi zomthofu kubhekane nemikhawulo ekhulayo yokulawula ngenxa yokukhathazeka kwemvelo nempilo okuhambisana nokuchayeka komthofu. Umthofu uyinto enobuthi, futhi ukusetshenziswa kwawo emikhiqizweni ethengwayo nasezintweni zokwakha kunqunyelwe noma kuvinjelwe ezifundeni ezihlukahlukene.

 

Ukushintshela kwezinye izindlela:

 

Ukusabela emithethweni yezemvelo nempilo, imboni ye-PVC isishintshele kwezinye iziqinisi ezinomthelela ophansi kwezemvelo. Iziqinisi ezisekelwe ku-calcium, iziqinisi ze-organotin, nezinye izindlela ezingezona eziholayo ziya ngokuya zisetshenziswa ekwakhiweni kwe-PVC.

 

Umthelela Wezemvelo:

Ukusetshenziswa kwezinqamuleli zomthofu kuye kwaphakamisa ukukhathazeka mayelana nokungcoliswa kwemvelo kanye nokuchayeka komthofu okungaba khona. Ngenxa yalokho, kuye kwenziwa imizamo yokunciphisa ukuthembela kuzinzinzisi zomthofu ukuze kuncishiswe umthelela wazo kwezemvelo.

 

Kubalulekile ukuqaphela ukuthi uguquko olusuka kuzinzinzisi zomthofu lubonisa ukuthambekela okubanzi okuya ezinkambisweni ezinobungani nemvelo kanye nokunaka impilo embonini ye-PVC. Abakhiqizi nabasebenzisi bayakhuthazwa ukuthi basebenzise ezinye izindlela ezihlangabezana nezidingo zokulawula futhi bafake isandla ekusimameni. Hlala unolwazi mayelana nemithetho yakamuva kanye nezinqubo zemboni mayelana nokusetshenziswa kwezinzisi.
