Iingenelo zeziqinisi zetyuwa yelothe ziquka:
1. Uzinzo oluhle lobushushu: Ngenxa yokuba ikwazi ukucoca, ingathatha indawo yeeathom zekhlorine ezingazinzanga, umxholo ophezulu wesinyithi, kunye nokukwazi ukufunxa i-HCl.
2. Ubushushu bombane obuhle kakhulu: Ixabiso eliphantsi.
3. Ukumelana nokukhanya okugqwesileyo: Ezinye iintlobo zinobumanzi obuhle. Ezifana ne-lead dihydrogen phosphate, zinozinzo oluhle, i-antioxidant kunye ne-UV shielding effects, kwaye zinokunika iiprofayili uzinzo oluhle lokukhanya kunye nozinzo lwe-oxygen yobushushu bangaphandle, kunye nokuthamba komphezulu. Ukudibanisa ne-TiO2 kunokunciphisa inani le-UV absorbers kunye ne-antioxidants ezisetyenziswayo, kwaye i-Hechuan yeyona nkqubo izinzileyo esetyenziswa kakhulu kwiiprofayili ze-PVC eTshayina.
4. Ukusebenziseka kakuhle: Ifanelekile kwiindlela ezahlukeneyo zokucubungula kwaye inomsebenzi wombala omhlophe.
Iingxaki zokuqinisa ityuwa yelothe ziquka:
1. Uthuli olukhulu: Ngexesha lokusetyenziswa, kukho uthuli oluninzi kunye nokulinganisa okuninzi, okunokukhokelela kwiimpazamo zokulinganisa kwaye kube nefuthe elikhulu kumgangatho weeprofayili, okubangela ungcoliseko. Ukuphefumla uthuli kuyityhefu emzimbeni womntu.
2. Amathuba okusebenzisa utshintsho lombala oluhlaza okwesibhakabhaka ayanda.
3. Ityuwa ye-lead ye-monomer iya kubola nge-resin ye-PVC kwiprofayili ukuvelisa i-HCl kunye ne-PbCl2: iya kubangela ukuna okuqhubekayo kwee-ion zesinyithi. Xa zifudukela kumphezulu weprofayili, kwiindawo ezinongcoliseko olukhulu lwesulfure, ungcoliseko lwe-sulfur ludla ngokuvela, nto leyo ekhokelela ekutshintsheni kombala weprofayili. Ke ngoko, ii-agents zokugquma ze-lead cadmium ion, ii-agents ze-chelating, njl. kufuneka zongezwe kwifomyula yetyuwa ye-lead. Umsebenzi wazo kukwenza ii-complexes ezinokungcola okufana nee-chloride eziveliswa yiprofayili, ukuthintela ukuna kwee-chloride zesinyithi ezingahambelani kakuhle, kunye nokuthintela ungcoliseko lwe-sulfurization kunye nokutshintsha kombala.
4. Ukungasasazeki kakuhle: Izinto ezigcina ityuwa yelothe zisasazeki kakuhle.
5. Ityhefu ephezulu: Izinto ezigcina ityuwa yelothe ziyingozi kakhulu.
6. Impawu zokuqala zokufaka umbala: Iziqinisi zetyuwa yelothe zinophawu lokuqala lokufaka umbala, nto leyo eyenza kube nzima ukufumana iimveliso ezibonakalayo kunye neemveliso ezinemibala ecacileyo.
7. Ukungabikho kokuthambisa: Izinto ezigcina ityuwa yelothe zingenako ukuthambisa kwaye zisengozini yongcoliseko lwesalfure.
Ngamafutshane, izinto ezigcina ityuwa yelothe zineengenelo ezikhethekileyo ekucutshungulweni kweplastiki, kodwa kukwakho neengxaki ezibalulekileyo ezingenakubethwa ngoyaba. Kwimisebenzi ebonakalayo, kuyimfuneko ukuqwalasela ngokupheleleyo ezi zinto kunye nokuthatha amanyathelo afanelekileyo ukoyisa ukusilela kwazo.
