Amaphuzu okunakwa kunqubo yokubumba umjovo we-PVC

I-PVC iyinto ezwela ukushisa, futhi inqubo yayo yokubumba umjovo ayilungile.Isizathu siwukuthi izinga lokushisa eliphakeme kakhulu lokuncibilika noma isikhathi eside sokushisa singabola kalula i-PVC.Ngakho-ke, ukulawula izinga lokushisa lokuncibilika kuyisihluthuleloumjovo ukubumba imikhiqizo ye-PVC.Umthombo wokushisa wokuncibilikisa izinto zokusetshenziswa ze-PVC uvela ezicini ezimbili, okungukuthi, ukushisa kwe-shear kwepulasitiki okukhiqizwa ukunyakaza kwesikulufa kanye nokushisisa kwentambo yokumelana yodonga olungaphandle lomgqomo, okuwukushisa kwe-shear kokunyakaza kwesikulufu.Ukushisa kwangaphandle komgqomo ngokuyinhloko kuwumthombo wokushisa onikeziwe lapho umshini uqalwa.

I-PVC yayijwayele ukuba ipulasitiki enkulu kunazo zonke emhlabeni enezinjongo eziningi ezihlukahlukene, ikakhulukaziAmapayipi e-PVC nokufakwa.

Amaphuzu alandelayo azoqashelwa ekwakhiweni komkhiqizo kanye nokwakhiwa kwesikhunta:

1. Umkhiqizo akufanele ube namakhona abukhali noma izinguquko eziphuthumayo ngangokunokwenzeka, futhi ukushuba ngeke kushintshe kakhulu ukuvimbela ukuwohloka kwe-PVC.

2. Isikhunta kufanele sibe ne-engeli yokusalungiswa engaphezu kwamadigri ayi-10, futhi ukuncipha okungaba ngu-0.5% kuzogcinwa.

3. Amaphuzu amaningana kufanele anakwe ekwakhiweni komzila wokugeleza wesikhunta

A. Imbobo yomjovo yesikhunta izoba nkulu kancane kunembobo yombhobho futhi ibe nkulu kunobubanzi bempambanondlela yesiteshi esikhulu sokugeleza, ukuze okubalulekile kwe-PVC kungagelezi kumgodi wokukhunta futhi nokucindezela kulingane.

B. Isango elisikiwe lizosetshenziswa ngangokunokwenzeka ukuze kuvinjelwe i-slag encibilikisiwe ukuthi ingagelezi emkhiqizweni kanye nezinga lokushisa kumgijimi ukuba linciphe futhi kwenze kube lula ukukwakheka.

C. Isango lizoklanywa odongeni oluwugqinsi lomkhiqizo olunobubanzi obanele nobude obuyi-6-8mm ukwenza impahla ye-PVC ihambe kahle.

D. Ukuze usekele ukwehla kwengcindezi nokudiliza kalula, umzila wokugeleza kufanele ube yindilinga, futhi ububanzi kufanele bube ngu-6-10mm ngokuya ngosayizi womkhiqizo nesisindo.

4. Izinga lokushisa lesikhunta kufanele lifakwe idivayisi yokulawula amanzi okupholisa ukwenza izinga lokushisa lesikhunta lilawuleke phakathi kuka-30 ℃ no-60 ℃.

5. Ingaphezulu lesikhunta lizoba bushelelezi futhi lihlanzeke, futhi i-chrome plating izosetshenziselwa ukuvimbela ukugqwala.
