1. Cov txheej txheem tsim khoom ntawm cov khoom yas yog cov txheej txheem molding ntawm lub raj mis yas, uas yog hais txog cov txheej txheem ntawm kev ua cov khoom yas zoo kawg nkaus los ntawm cov polymer uas tsim los ntawm cov khoom siv hluavtaws.

2. Cov txheej txheem ua haujlwm (thiab kev ua cov yas) muaj xws li: siab molding (moulding), extrusion (extrusion molding), txhaj tshuaj molding (txhaj tshuaj molding), tshuab moulding (hollow molding), calendering, thiab lwm yam kev tsim tshwj xeeb:

⑴ siab molding: molding los yog nias molding.Nws yog tsuas yog siv rau molding thermosetting yas xws li phenolic resin, urea-formaldehyde resin thiab unsaturated polyester resin.

⑵ extrusion: extrusion molding, yog siv lub tshuab extrusion (extruder) yuav rhuab resin tas li los ntawm cov pwm, extrusion xav tau cov qauv ntawm cov khoom, Extrusion kuj qee zaum siv hauv thermosetting yas molding, thiab tuaj yeem siv rau hauv molding ntawm Ua npuas ncauj plastics.Qhov zoo ntawm extrusion yog tias nws tuaj yeem extrude ntau yam duab ntawm cov khoom, kev ua haujlwm siab ntau lawm, tsis siv neeg thiab nruam ntau lawm; Qhov tsis zoo yog tias thermosetting yas hlua tsis tuaj yeem siv dav hauv cov qauv ntawm kev ua, cov khoom loj yooj yim tsim deviation. .

⑶ Txhaj tshuaj molding: txhaj tshuaj molding.Kev txhaj tshuaj molding yog kev siv lub tshuab txhaj tshuaj molding (los yog lub tshuab txhaj tshuaj) rau cov hlua thermoplastic yaj nyob rau hauv siab siab rau hauv pwm tom qab txias, solidification kom tau cov khoom txoj kev.Injection molding kuj yuav siv tau rau thermosetting plastics. thiab ua npuas ncauj yas hlua molding.Kev txhaj tshuaj molding muaj qhov zoo ntawm cov khoom siv ceev ceev, kev ua haujlwm siab, tsis siv neeg manipulation, thiab tuaj yeem tsim cov khoom siv, tshwj xeeb tshaj yog tsim rau cov khoom loj.Qhov tsis zoo yog cov nqi ntawm cov khoom siv thiab pwm yog siab, thiab kev txhaj tshuaj. lub tshuab molding yog qhov nyuaj los ntxuav.

⑷ tshuab moulding: hollow tshuab molding los yog hollow molding.Blow molding yog ib txoj kev ntawm tshuab hollow khoom los ntawm lub siab ntawm compressed cua kom cov kub resin billet kaw nyob rau hauv lub pwm.Tshuab moulding muaj xws li ob txoj kev tshuab moulding zaj duab xis thiab tshuab molding hollow cov khoom.With tshuab moulding txoj kev tuaj yeem tsim cov khoom ua yeeb yaj kiab, ntau lub raj mis, thoob, POTS thiab cov menyuam yaus cov khoom ua si.

⑸ Calendering: Nws yog txoj kev molding uas cov resin thiab ntau yam khoom siv tau ua tiav (kneading, filtering, thiab lwm yam) rau hauv cov yeeb yaj kiab lossis cov ntawv los ntawm qhov khoob ntawm ob lossis ntau qhov sib txawv calendering rollers ntawm lub calender, uas yog tom qab ntawd tshem tawm cov menyuam ntawm lub calender, thiab ces shaped los ntawm txias.Calendering yog tsuas yog siv nyob rau hauv polyvinyl chloride resin molding txoj kev, yuav ua tau zaj duab xis, ntawv, phaj, dag tawv, pem teb vuas thiab lwm yam khoom.

Yantai Dongyuan Plastic Products Co., Ltd.PE yas hlua net, North Korean hemp (PP) cov khoom siv net, tshuaj chiv hoisting net, khoom hoisting net, tsheb sealing net, kev ruaj ntseg net, yug hlua, nkoj sab kev nyab xeeb net thiab ntau yam tshwj xeeb specifications ntawm tes-woven hoisting net, kev ruaj ntseg net, feem ntau yog siv nyob rau hauv chaw nres nkoj, tshuaj chiv ntau lawm enterprises, nplej thiab roj ua lag luam ntawm soybean noj mov cia thiab thauj.Polyethylene (PE) thiab Korean hemp (PP) ropes mas siv nyob rau hauv kev lag luam, kev ua liaj ua teb. thiab nuv ntses.
