1. Isicelo kanye Nokulungiselela Kafushane:
Impahla ekhethekile ye-polypropylene enamathela isetshenziselwa ikakhulukazi ukumbozwa kwesikhwama esilukiwe se-polypropylene nendwangu elukiwe. Ngemuva kokumboza, izikhwama ezilukiwe ezenziwe nge-coating zingasetshenziswa ngokuqondile ngaphandle kwezikhwama ze-polyene. amandla kanye nokusebenza okuphelele kwesikhwama esilukiweyo kuyathuthukiswa ngoba ifilimu ye-polypropylene circulation ihlanganiswe ngokuqondile esikhwameni esilukiweyo, futhi ukusetshenziswa kulula, futhi izindleko zokukhiqiza nazo ziyancipha.

I-State Building Materials Agency (i-National Building Materials Bureau) yasungula amagama athi & lt;1997>No.079 ngoNovemba 1997, ibeka ukuthi izikhwama ezilukiwe ezenziwe ngamalambu kufanele zisetshenziselwe ukupakisha usimende neminye imikhiqizo. Ngasikhathi sinye, ngokuthuthukiswa kwemboni yokupakisha yasekhaya, uhla lokusebenzisa kanye nomthamo webanga likapende le-PP lakhula kancane kancane. Umkhiqizi wokuqala wepulasitiki uthenge ulayini wokukhiqiza wepulasitiki kanye nezikhwama eziyinhlanganisela ezilukiwe, ezishintshiwe zisuka esikhwameni sangaphakathi se-PE sangaphakathi esiyi-PP saba isikhwama sekhava esikabili-koyedwa kanye nesikhwama esiyinhlanganisela sephepha se-3-in-one, kanye nesidingo semakethe sebanga. I-PP ikhula usuku nosuku. Ukunikezwa kwe-PP yebanga likapende wasekhaya kuqinile.
kunikezwe okungenhla, sisekelwe ku-T30S evamile kanye ne-2401 (MFR = 2 ~ 4 g / 10min) futhi sathuthukisa ngempumelelo izinto ezikhethekile zebanga lokuhlanganisa (MFR = 20 ~ 32 min, amandla aqinile 24.0 MPa) ngokusebenzisa ukuchithwa okulawulwayo ngemva kokuxuba.

Phakathi nenqubo yokuthuthukisa, kwenziwa izivivinyo eziningana ekukhethweni kwezilawuli zesisindo samangqamuzana nezinye izinto ezisizayo, ukuxutshwa nokufakwa kwepulasitiki kwezinto ezingavuthiwe kanye nemingcele yenqubo ehlobene. Ngemuva kokuhlolwa okuthuthukisiwe, inqubo yokwakhiwa kanye nokukhiqizwa kwezingubo ze-PP zanqunywa. yakha umugqa wokukhiqiza ngobuningi. imiphumela egculisayo itholakale ngokusebenzisa izinhlelo zokusebenza eziningi, ezihlala zibonisa ikhwalithi ezinzile yomkhiqizo, ukuncibilika okuhle kwe-melt, ukwakheka kwefilimu efanayo, ukuncipha okuphansi, amandla e-peel aphezulu kanye nokunamathela okuphezulu. 2. izinzuzo zezomnotho ezicatshangelwayo:

Intengo yezinto ezikhethekile ngethani ngalinye lokumboza cishe i-2,000 yuan ephakeme kunentengo yezinto zokusetshenziswa. Ngemva kokudonsa izesekeli, abasebenzi, izinsiza, ukwehla kwamandla emishini kanye nezinye izindleko zamayuan angu-150, inzuzo yonke ngethani lezinto ezikhethekile ingu-1500 yuan. Umkhiqizo wonyaka womugqa wokukhiqiza (obalwa yi-extruder enobubanzi obuyi-screw ka-65) ungamathani angama-350-450, futhi intela yentela yonyaka ingafinyelela ngaphezu kwama-yuan angama-500000. uma usebenzisa i-screw extruder enkulu, ukukhiqiza kuphezulu. Njengamanje, i-China inezimboni zezikhwama ezinkulu ezilukiwe ezingaphezu kuka-1000, amadolobhana namadolobhana kanye namabhizinisi azimele ezingenakubalwa. Iphrojekthi inamathemba abanzi.
Okwesibili, ubuchwepheshe bokulungiselela i-polypropylene cooling masterbatch ye-polypropylene cooling masterbatch iyi-polypropylene-based masterbatch, ikakhulukazi esetshenziselwa ukunciphisa izinga lokushisa le-polypropylene ukuphotha kanye nemikhiqizo yepulasitiki ekucutshungulweni, ikakhulukazi ku-polypropylene ukuphotha umphumela omuhle kakhulu, kodwa futhi isetshenziselwa ukukhiqizwa kokufutha kwe-polypropylene. ifilimu, izikhwama zendwangu, i-monofilament, imikhiqizo yokubumba umjovo nayo ithole imiphumela emihle.
inkomba yokusebenza eyinhloko: engeza i-1 ~ 5% yokupholisa i-masterbatch ku-polypropylene resin ukuze icutshungulwe; ingafinyelela amaphuzu alandelayo: wonke amamaki e-polypropylene resin angakhiqiza ikhwalithi ephezulu ye-C eyindilinga ye-fine denier fiber. Izinga lokushisa lokuphotha nokucubungula ipulasitiki lingancishiswa lisuka ku-20°C liye ku-50°CC; ngcono ikhwalithi ye-polypropylene fiber kanye nemikhiqizo yepulasitiki; ngcono ukusebenza kahle kokukhiqiza; kanye nokunciphisa ukungcoliswa kwemvelo.

Ububanzi bokusebenza: ukuphotha kwe-polypropylene, ukufutha kwefilimu ye-polypropylene, izikhwama ezilukiwe ze-polypropylene, i-monofilament
