1. Chikumbiro uye Kugadzirira Pfupiso:
Iyo yakakosha zvinhu zvepolypropylene coating inonyanya kushandiswa kupfekedza yepolypropylene yakarukwa bhegi nemucheka wakarukwa. Mushure mekuputira, mabhegi akarukwa akagadzirwa nejasi anogona kushandiswa zvakananga pasina jira re polyene mabhegi. kusimba uye kuita kwese kwebhegi rakarukwa kunovandudzwa nekuti iyo polypropylene circulation firimu inonamira pabhegi rakarukwa, uye kushandiswa kuri nyore, uye mutengo wekugadzira wakaderedzwa zvakare.

Sangano reState Building Materials Agency (National Building Materials Bureau) rakagadzira mazwi ekuti & lt;1997>No.079 muna Mbudzi 1997, richitara kuti masaga akarukwa anofanirwa kushandiswa kurongedza simende nezvimwe zvinogadzirwa. Panguva imwecheteyo, nekuvandudzwa kweindasitiri yekurongedza yepamba, huwandu hwekushandisa uye dosi yependi giredhi PP yakawedzera zvishoma nezvishoma. Mugadziri wepurasitiki wepakutanga akatenga mutsara wekugadzira epurasitiki nemabhegi akarukwa akaumbwa, akachinja kubva kune yekutanga PE yemukati bhegi PP yakarukwa bhegi kuenda maviri-mu-rimwe bhegi rekuvhara uye matatu-mu-rimwe mapepa epurasitiki composite bhegi, uye kudiwa kwemusika kwegiredhi. PP iri kuwedzera zuva nezuva. Yemukati pendi giredhi PP inopa yakasimba.
takapihwa zviri pamusoro, isu takavakirwa pane zvakajairika T30S uye 2401 (MFR = 2 ~ 4 g / 10min) uye zvakabudirira kugadzira zvakakosha zvegiredhi rejasi (MFR = 20 ~ 32 min, tensile simba 24.0 MPa) kuburikidza nekudzora kuderedzwa mushure mekusanganiswa.

Munguva yekuvandudza maitiro, zviedzo zvakati wandei zvakaitwa pakusarudzwa kwema molecular weight regulators uye zvimwe zvinobatsira, kusanganisa uye plasticizing yezvakagadzirwa uye zvine chekuita nemaitiro paramita. Mushure mekuongorora kwakagadziridzwa, kuumbwa uye kugadzirwa kwePP coating kwakatemwa. gadzira mutsara wekugadzira ruzhinji. mhedzisiro inogutsa yakawanikwa kuburikidza neakawanda maapplication, ayo anogara achiratidza yakagadzikana mhando yechigadzirwa, yakanaka melt fluidity, yunifomu yefirimu kuumbwa, yakaderera shrinkage, yakakwirira peel simba uye yakakwirira kunamatira. 2. Zvinofungidzirwa mabhenefiti ehupfumi:

Mutengo wezvinhu zvakakosha patani yekupfekedza inenge 2,000 yuan yakakwirira kudarika mutengo wezvigadzirwa. Mushure mekubvisa zvishongedzo, vashandi, zvekushandisa, kudzikira kwemagetsi uye zvimwe zvinodhura zve150 yuan, iyo purofiti patani yezvinhu zvakakosha i1500 yuan. Kubuda kwepagore kwemutsara wekugadzira (yakaverengerwa neextruder ine screw dhayamita ye65) ndeye 350-450 matani, uye wepagore net mutero unogona kusvika kupfuura 500000 yuan. kana iwe ukashandisa yakakura screw extruder, chibereko chakakwira. Parizvino, China ine anopfuura 1000 makuru akarukwa mafekitori emabhegi, misha nemataundi nemabhizinesi akazvimirira asingaverengeki. Chirongwa chine tarisiro yakakura.
Chechipiri, tekinoroji yekugadzirira yepolypropylene cooling masterbatch polypropylene cooling masterbatch is polypropylene-based masterbatch, inonyanya kushandiswa kuderedza tembiricha yepolypropylene kuruka uye zvigadzirwa zvepurasitiki mukugadziriswa, kunyanya mu polypropylene kuruka kwakanakisa, asi zvakare inoshandiswa mukugadzirwa kwepolypropylene kufefetera. firimu, mabhegi emachira, monofilament, jekiseni rekugadzira zvigadzirwa zvakawanawo mhedzisiro yakanaka.
main performance index: wedzera 1 ~ 5% inotonhorera masterbatch kune polypropylene resin yekugadzirisa; inogona kuwana mapoinzi anotevera: ese magiredhi epolypropylene resin anogona kuburitsa yakakwira mhando C yakatenderedza yakanaka denier fiber. Kutenderera uye kupisa kwepurasitiki yekugadzirisa kunogona kuderedzwa kubva pa20 ° C kusvika ku50 ° C; kunatsiridza kunaka kwe polypropylene fiber uye zvigadzirwa zvepurasitiki; kuvandudza kushanda kwekugadzira; uye kuderedza kusvibiswa kwezvakatipoteredza.

Chiyero chekushandisa: polypropylene kuruka, polypropylene firimu kuvhuvhuta, polypropylene yakarukwa mabhegi, monofilament
