Izinzisi zelothe, njengoko igama lisitsho, luhlobo lwe-stabilizer esetyenziswa ekuvelisweni kwe-polyvinyl chloride (PVC) kunye nezinye ii-polymers ze-vinyl. Ezi stabilizers ziqulathe iikhompawundi ze-lead kwaye zongezwa kwi-PVC formulations ukuthintela okanye ukunciphisa ukonakala kobushushu be-polymer ngexesha lokucubungula nokusetyenziswa.Iziqinisi ze-lead kwi-PVCbezisetyenziswa kakhulu kwimbali kwishishini le-PVC, kodwa ukusetyenziswa kwazo kuye kwehla kwezinye iindawo ngenxa yeengxaki zokusingqongileyo kunye nempilo ezinxulumene nelothe.
Amanqaku aphambili malungaiziqinisi zelotheziquka:
Indlela Yokuzinzisa:
Iziqinisi zelothe zisebenza ngokuthintela ukuwohloka kobushushu bePVC. Ziyayithomalalisa imveliso yeasidi eyenziwe ngexesha lokuqhekeka kwePVC kumaqondo obushushu aphezulu, zithintela ukulahleka kobume bepolymer.
Izicelo:
Iziqinisi zelothe bezisetyenziswa ngokwesiko kwiintlobo ngeentlobo zezicelo zePVC, kubandakanya imibhobho, ukufakelwa kwentambo, iiprofayili, amaphepha, kunye nezinye izinto zokwakha.
Uzinzo lobushushu:
Zibonelela ngokuzinzisa ubushushu ngempumelelo, zivumela i-PVC ukuba icutshungulwe kumaqondo obushushu aphezulu ngaphandle kokonakala okukhulu.
Ukuhambelana:
Iziqinisi zelothe zaziwa ngokuhambelana kwazo nePVC kunye nokukwazi kwazo ukugcina iipropati zoomatshini nezomzimba zepolymer.
Ukugcinwa kombala:
Zinegalelo ekuzinzeni kombala weemveliso zePVC, zinceda ekuthinteleni ukutshintsha kombala okubangelwa kukuwohloka kobushushu.
Izinto eziqwalaselwayo kwiMithetho:
Ukusetyenziswa kwezithinteli zelothe kuye kwajongana nemida eyandayo yemithetho ngenxa yeengxaki zokusingqongileyo nempilo ezinxulumene nokuvezwa kwelothe. Ilothe yinto enobuthi, kwaye ukusetyenziswa kwayo kwiimveliso zabathengi kunye nezixhobo zokwakha kuye kwathintelwa okanye kwavalwa kwiindawo ezahlukeneyo.
Ukutshintshela kwezinye iindlela:
Ukuphendula kwimigaqo yokusingqongileyo nezempilo, ishishini le-PVC liye latshintshela kwezinye iindlela zokuqinisa ezinegalelo elincinci kwindalo. Izixhobo zokuqinisa ezisekelwe kwi-calcium, izixhobo zokuqinisa i-organotin, kunye nezinye iindlela ezingezizo i-lead zisetyenziswa kakhulu kwi-PVC formulations.
Impembelelo kwiNdalo:
Ukusetyenziswa kwezithambisi-ndlela zokuzinzisa ilothe kuphakamise inkxalabo malunga nongcoliseko lokusingqongileyo kunye nokuchaphazeleka kwelothe okunokwenzeka. Ngenxa yoko, kwenziwe imizamo yokunciphisa ukuxhomekeka kwizithambisi-ndlela zokuzinzisa ilothe ukunciphisa impembelelo yazo kokusingqongileyo.
Kubalulekile ukuqaphela ukuba ukutshintsha ukusuka kwizinto ezigcina i-lead stabilizers kubonisa umkhwa obanzi ojolise kwiindlela ezinobuhlobo nokusingqongileyo kunye nezempilo kwishishini le-PVC. Abavelisi kunye nabasebenzisi bayakhuthazwa ukuba basebenzise ezinye iindlela ezihlangabezana neemfuno zomthetho kwaye zinegalelo ekuzinzeni. Hlala unolwazi malunga nemithetho yamva nje kunye neendlela zoshishino malunga nokusetyenziswa kwezinto ezigcina i-lead stabilizer.
