I-PVC yinto ebuthathaka kubushushu, kwaye inkqubo yayo yokubumba inaliti imbi.Isizathu kukuba ubushushu obuphezulu bokunyibilika okanye ixesha elide lokufudumeza linokubola ngokulula iPVC.Ngoko ke, ukulawula ubushushu obunyibilikayo ngundoqoisitofu sokubumba iimveliso zePVC.Umthombo wobushushu ukunyibilika PVC izinto ekrwada livela kwimiba emibini, ezizezi, ukucheba ubushushu zeplastiki eziveliswe sisindululo Screw kunye ukuxhathisa ngocingo ukufudumeza yodonga lwangaphandle umphanda, nto leyo ubukhulu becala ubushushu ukucheba intshukumo screw.Ukufudumeza kwangaphandle kombhobho ikakhulu ngumthombo wobushushu onikezelweyo xa umatshini uqaliswa.
I-PVC yayiyeyona njongo inkulu yeplastiki yehlabathi enoluhlu olubanzi lwezicelo, ikakhuluImibhobho yePVC kunye nokufakelwa.
La manqaku alandelayo aya kuqatshelwa kuyilo lwemveliso kunye noyilo lokungunda:
1. Imveliso ayiyi kuba neekona ezibukhali okanye utshintsho olukhawulezayo kangangoko kunokwenzeka, kwaye ubukhulu abuyi kutshintsha kakhulu ukuthintela ukuthotywa kwePVC.
2. Isikhunta siya kuba ne-angle eyidrafti yee-degrees ezingaphezu kwe-10, kwaye i-shrinkage malunga ne-0.5% iya kugcinwa.
3. Amanqaku amaninzi kufuneka ahlawulwe ingqalelo kwi-design ye-flow channel ye-mold
A. Isango lokutofa lokungunda liya kuba likhulu kancinane kunomngxuma wombhobho kwaye libe likhulu kunobubanzi besiphambuka somjelo ophambili wokuqukuqela, ukuze izinto zePVC zingaphumi kumgodi wokungunda kwaye uxinzelelo lunokulingana.
B. Isango lokusikwa liya kusetyenziswa kangangoko kunokwenzeka ukukhusela i-slag etyhidiweyo ukuba ingagelezi kwimveliso kunye neqondo lokushisa kwimbaleki ekunciphiseni kwaye kube lula ukwenza.
C. Isango liya kuyilwa eludongeni olutyebileyo lwemveliso enobubanzi obaneleyo kunye nobude obuyi-6-8mm ukwenza izinto zePVC zihambe kakuhle.
D. Ukuze kuxhaswe ukuhla koxinzelelo kunye nokuchithwa ngokulula, umjelo wokuhamba kufuneka ube ngeenxa zonke, kwaye ububanzi bube yi-6-10mm ngokwesayizi yemveliso kunye nobunzima.
4. Iqondo lobushushu lokungunda liya kuxhotyiswa ngesixhobo sokulawula amanzi okupholisa ukwenza iqondo lobushushu lokungunda lilawuleke phakathi kwe-30 ℃ kunye ne-60 ℃.
5. Umphezulu wokubumba uya kuba mpuluswa kwaye ucoceke, kwaye i-chrome plating iya kusetyenziswa ukukhusela ukubola.
