Zithini iziphumo zabalawuli be-PVC foaming kwisakhiwo seembobo zeemveliso

Umlawuli we-foam owenziwe yiBontecn Group China uchaphazela ngokuthe ngqo ukwakheka, uzinzo, kunye nolwakhiwo lokugqibela lwee-foam pores ngokulawula iipropati ze-polymer melts. Iimpawu ezithile zezi zilandelayo:
1. Ukufana kunye nokuphuculwa kweembobo zefoam
Yomeleza amandla kunye nokuqina kwe-melt, khuthaza ukusasazwa okufanayo kwegesi kwi-PVC melt, yenza ii-micropores ezizimeleyo (ububanzi obuyi-0.1-0.5mm), kwaye unciphise ingxaki yokudibana kwamaqamza okanye ukuqina. Kwangaxeshanye, phucula ukuhlangana kwe-melt ukuqinisekisa ukuba iindonga zeseli ziyakwazi ukumelana noxinzelelo lwegesi kwaye zigcine uzinzo lwesakhiwo seseli esivaliweyo.
2. Uxinano lweeseli kunye nolawulo lobungakanani
Umlinganiselo kufuneka ulinganiswe ngokuchanekileyo: uphantsi kakhulu (<4phr) ukhokelela ekubeni amandla okunyibilika anganele, okubangela ukuqhekeka kwamaqamza okanye ukuwa komphezulu; Ukuba uphezulu kakhulu (>8phr), uya kuyiqinisa kakhulu inyibilike, ucinezele ukwanda kwamaqamza, kwaye endaweni yoko wonyuse uxinano lwemveliso. Okukhona ubunzima bemolekyuli buphezulu (njengemodeli ye-530), kokukhona ama-pores ecolile kwaye anciphise uxinano, kodwa inovelwano kubushushu bokucubungula.
3. Ukuthintela iziphene kunye nokwenza ngcono ulwakhiwo
Ukuthintela amaqamza angaqhelekanga (afana namaqamza amade okanye amehlo eentlanzi), kuyimfuneko ukulungelelanisa inkqubo yokuthambisa kunye nobushushu benkqubo: ukutyibilika okugqithisileyo kwangaphandle kuya kunciphisa uxinzelelo lokunyibilika kwaye kubangele ukungalingani koxinano lwendawo; Ukutshintshatshintsha kobushushu be-± 5 ℃ kunokuphazamisa ukufana kweembobo kwaye kufuneke ukongezwa kwezinto eziguqulayo ezifana ne-zinc stearate ukuze kulinganiswe.
4. Ukuguquguquka okuguquguqukayo
Ukukhethwa kwemodeli (efana ne-KF-100) kwiintlobo ezahlukeneyo zeemveliso (ezifana namaphepha e-PVC aqinileyo okanye izinto zezihlangu ezithambileyo) kuchaphazela ngqo ulwakhiwo lwemingxuma: kwiimveliso ezithambileyo, kufuneka umlawuli okhethekileyo ukuze kuthintelwe ukudumba kolusu nokuphucula ukuthamba.
