Firimu reStretch, iro rinozivikanwawo seStretch Film neHeat Shrink Film, rakatanga kugadzirwa muChina richishandisa PVC sechinhu chepasi uye DOA seplasticizer uye rinozvinamira rePVC stretch film. Nekuda kwematambudziko ezvakatipoteredza, kudhura kwakanyanya (zvichienderana nePE, nzvimbo shoma yekurongedza payuniti) uye kusatambanuka zvakanaka, PE stretch film yakabviswa pakupera apo kugadzirwa kwemumba kwakatanga muna 1994-1995. Chinhu chepasi chinonyanya kugadzirwa neLLDPE, kusanganisira C4, C6, C8 uye metallocene PE (MPE).
Zvinhu
Inogadzirwa nekushandisa LLDPE resin uye tackifier special additives proportional formula inopinzwa kunze kwenyika, uye inogona kugadzira multifunctional winding film yemaoko, resistance type machine, pre-stretch type machine, anti-UV, anti-static uye anti-ngura. Ine mabhenefiti anotevera:
1. Uchishandisa michina yekuwedzera jira rine mativi maviri, firimu rinomonereka rinogona kuwedzera hunhu hwepolymer yega yega, kujeka kwayo, simba rayo rekudhonza, uye kuramba kubooka, kusvika padanho rakakodzera panguva yekunyunguduka.
2. Ine hunhu hwakanaka hwekusunga, kujeka kwakanaka, uye ukobvu hwakaenzana.
3. Ine kureba kwenguva refu, yakasimba, inodzivirira kubvaruka yakatwasuka zvakanaka, uye inozvinamira zvakanaka pamakumbo.
4. Chinhu chinogadziriswazve chine hushamwari kune zvakatipoteredza, hachina kunaka, hachina chepfu, chinogona kuputirwa zvakananga muchikafu.
5. inogona kugadzira zvigadzirwa zvinonamira zvine divi rimwe chete, kuderedza ruzha runobuda panguva yekumonera nekutambanudza, kuderedza guruva nejecha panguva yekufambisa nekuchengetedza.
Kushandiswa
1. Kurongedza kwakavharwa
Rudzi urwu rwekurongedza rwakafanana nekurongedza zvidimbu zvefirimu, uko firimu rinoputirwa papallet kuti riputirwe, uye zvino zvigadziko zviviri zvinopisa zvinosunga firimu kumativi ese ari maviri pamwe chete. Iyi ndiyo fomu yekutanga yefirimu rinoputirwa uye yakatungamira mukugadzirwa kwemamwe marudzi akawanda ekurongedza.
2. Kurongedza kwakazara
Rudzi urwu rwekurongedza runoda kuti firimu rive rakakura zvakakwana kuti rivhare pallet, iro rine chimiro chakajairwa, saka rakakodzera kushandiswa nefirimu rakakora kubva pa17 kusvika 35μm.
3. Kurongedza nemaoko
Rudzi urwu rwekurongedza ndirwo rudzi rwakareruka rwekurongedza firimu rekuputira, rinoiswa pasherufu kana neruoko, nekutenderedza pallet kana firimu rakatenderedza pallet. Rinonyanya kushandiswa pakurongedzazve mapallet akaputirwa mushure mekutyoka, uye pakurongedza kwakajairika kwepallet. Rudzi urwu rwekurongedza runononoka uye ukobvu hwakakodzera hwefirimu hunobva pa15 kusvika 20 μm.
