Kuwomba nkhungu kapangidwe ndi jekeseni nkhungu kufanana ndi kusiyana, ayenera kulabadira chiyani?

1. Kuwomba akamaumba nkhungu kapangidwe ndi osiyana, kuwomba akamaumba nkhungu kapangidwe ndi jekeseni + kuwomba;Jekeseni akamaumba ndi jekeseni + kuthamanga;Kupanga roll ndi extrusion + pressure;Kuwomba kuyenera kukhala ndi mutu wosiyidwa ndi chitoliro choyamwa, kuumba jekeseni kuyenera kukhala ndi gawo lachipata, kudula pulasitiki kuyenera kukhala ndi burr.

Kuwomba akamaumba kufa kapangidwe

2. Nthawi zambiri, jekeseni akamaumba ndi olimba pachimake, kuwomba akamaumba ndi mpukutu akamaumba ndi chopanda pakati.jekeseni mbali pamwamba ndi yowala, kuwomba ndi mayina pulasitiki pamwamba ndi wosagwirizana.Kuwomba akamaumba ndi mayina akamaumba kufananitsa osachepera kuwomba akamaumba ali ndi pakamwa kuwomba.Uku ndi kufananitsa wamba.Ndikudabwa ngati mukumvetsa!!

3. Kuchepa kwa mapulasitiki ndi zinthu zake zokopa

Thermoplastics ili ndi mphamvu yokulirapo ikatenthedwa, kutsika ikazizira, komanso kutsika ikapanikizika.Popanga jekeseni, pulasitiki yosungunuka imalowetsedwa mu nkhungu, itatha kudzazidwa, kusungunula kumasungunuka ndikukhazikika, ndipo shrinkage imachitika pamene zigawo za pulasitiki zimachotsedwa mu nkhungu, zomwe zimatchedwa kupanga shrinkage.Zigawo za pulasitiki kuchokera ku nkhungu mpaka kukhazikika kwa nthawiyi, padzakhalabe kusintha kwakung'ono mu kukula, kusintha kumapitirizabe kuchepa, shrinkage iyi imatchedwa post-shrinkage.Kusiyana kwina ndikukula kwa mapulasitiki ena a hygroscopic chifukwa cha kuyamwa kwa chinyezi.Mwachitsanzo, pamene madzi a nayiloni 610 ali 3%, kukula kwake ndi 2%;Pamene madzi okhutira galasi CHIKWANGWANI analimbitsa nayiloni 66 ndi 40%, kukula kukula ndi 0,3%.Koma kupanga shrinkage kumagwira ntchito yaikulu.
