Iziqinisi zomthofu, njengoba igama lisikisela, uhlobo lwe-stabilizer olusetshenziswa ekukhiqizweni kwe-polyvinyl chloride (PVC) kanye namanye ama-polymer e-vinyl. Lawa ma-stabilizer aqukethe ama-compounds e-lead futhi anezelwa ekwakhiweni kwe-PVC ukuvimbela noma ukunciphisa ukuwohloka kokushisa kwe-polymer ngesikhathi sokucubungula nokusetshenziswa.Iziqinisi zokuhola ku-PVCbezisetshenziswa kabanzi embonini ye-PVC ngokomlando, kodwa ukusetshenziswa kwazo kwehlile kwezinye izindawo ngenxa yezinkinga zemvelo nezempilo ezihlobene nomthofu.
Amaphuzu abalulekile mayelanaiziqinisi zomthofufaka:
Indlela Yokuzinzisa:
Iziqinisi zomthofu zisebenza ngokuvimbela ukuwohloka kokushisa kwe-PVC. Ziqeda imikhiqizo engaba yi-asidi eyakheka ngesikhathi sokuwohloka kwe-PVC emazingeni okushisa aphezulu, zivimbela ukulahlekelwa ubuqotho besakhiwo se-polymer.
Izicelo:
Iziqinisi zomthofu bezisetshenziswa ngokwesiko ezinhlotsheni ezahlukene ze-PVC, okuhlanganisa amapayipi, ukuvikela izintambo, amaphrofayili, amashidi, nezinye izinto zokwakha.
Ukuqina Kokushisa:
Zihlinzeka ngokuqina kokushisa okuphumelelayo, okuvumela i-PVC ukuthi icutshungulwe emazingeni okushisa aphezulu ngaphandle kokuwohloka okukhulu.
Ukuhambisana:
Iziqinisi ze-lead zaziwa ngokuhambisana kwazo ne-PVC kanye nekhono lazo lokugcina izakhiwo ze-polymer zisebenza kahle futhi zisebenza kahle.
Ukugcinwa Kombala:
Zinegalelo ekuzinzeni kombala wemikhiqizo ye-PVC, zisiza ekuvimbeleni ukubola kombala okubangelwa ukuwohloka kokushisa.
Izinto Okufanele Uzicabangele Ngokwemithetho:
Ukusetshenziswa kweziqinisi zomthofu kubhekane nemikhawulo yemithetho ekhulayo ngenxa yezinkinga zemvelo nezempilo ezihlobene nokuchayeka kumthofu. Umthofu uyinto enobuthi, futhi ukusetshenziswa kwawo emikhiqizweni yabathengi kanye nezinto zokwakha kuye kwanqunywa noma kwavinjelwa ezindaweni ezahlukene.
Ukushintshela Ezindleleni Ezihlukile:
Ngenxa yemithethonqubo yezemvelo nezempilo, imboni ye-PVC isishintshele kwezinye izindlela zokuqinisa ezinomthelela ophansi kwezemvelo. Izindlela zokuqinisa ezisekelwe ku-calcium, izindlela zokuqinisa i-organotin, kanye nezinye izindlela ezingezona i-lead zisetshenziswa kakhulu ekwakhiweni kwe-PVC.
Umthelela Wezemvelo:
Ukusetshenziswa kweziqinisi zomthofu kuphakamise ukukhathazeka mayelana nokungcoliswa kwemvelo kanye nokuchayeka okungenzeka komthofu. Ngenxa yalokho, kuye kwenziwa imizamo yokunciphisa ukuthembela kuziqinisi zomthofu ukuze kuncishiswe umthelela wazo emvelweni.
Kubalulekile ukuqaphela ukuthi ukushintshela ekuzinziseni i-lead kubonisa ukuthambekela okubanzi ekubhekeni emikhubeni enobungani nemvelo kanye nezempilo embonini ye-PVC. Abakhiqizi nabasebenzisi bakhuthazwa ukuthi basebenzise ezinye izindlela ezihlangabezana nezidingo zomthetho futhi zinegalelo ekuzinzeni. Hlala unolwazi ngemithethonqubo yakamuva kanye nemikhuba yemboni mayelana nokusetshenziswa kwezinzisekelo.
