zvigadzirwa

PVC firimu giredhi,
PVC yefirimu, PVC resin yeFlexible Vinyl Firimu, PVC resin yeRigid Vinyl Firimu,

Firimu rePVC risina plasticizer rinonzi rigid vinyl film, nepo plasticized PVC inonzi flexible vinyl film.
1.Flexible Vinyl Firimu

Flexible vinyl firimu rine zvakanaka zvipingamupinyi zvivakwa kuoiri uye girizi asi rinopinda oxygen.Iyo zvakare ine yakanaka kubatirira, kujeka kwakanyanya uye puncture inodzivirira.Zvinhu izvi zvinoita kuti PVC ishanduke inokodzera kurongedzerwa kwechikafu kuchengetedza nyama uye zvimwe zvinoparara zvinogadzirwa zvinyoro (kana FDA yatendera).Nekudaro, PVC ine purasitiki ine nzvimbo yakaderera yekunyunguduka, hainyanyi kushingirira kumakemikari, uye ine yakaderera yekupedzisira kusimba simba pane yakasimba vinyl.

2.Rigid Vinyl Firimu

Rigid vinyl, inozivikanwawo sekuti unplasticized polyvinyl chloride (uPVC), ifirimu rakasimba uye rakareruka.Ndiyo imwe yemafirimu anogara akadzikama uye anopesana nemakemikari akawanda.Kazhinji, uPVC inogona kushandiswa patembiricha inosvika 60°C.Iyo ine yakakwira tensile simba uye modulus pane inochinjika PVC, asi ine yakaderera maitiro kuomarara, uye iri pasi pekunetseka kwekupwanya zvichienderana nenharaunda.

PVC ine zvisingakwanisi uye zvipingamupinyi zvakawanda;iyo plasticizer inogona kuomesa mumamiriro ekutonhora uye kupfava pasi pemamiriro ekupisa, izvo zvinotungamirira kukuchinja kwezvinhu uye zvinogona kukanganisa simba rechisimbiso.PVC inoburitsawo zvidiki zvehydrogen chloride mumhepo uye inogadzira kabhoni dhipoziti pamidziyo yekuisa chisimbiso kana yapiswa.Nechikonzero ichi, kufefetedza kwakanaka kunodiwa pakusunga PVC shrink-wrap.

APPLICATIONS
Firimu rePVC rinoshandiswa sekudzikira uye kuputira kwezvigadzirwa zvemaindasitiri uye zvevatengi uye sekuputira pallet, zvisinei, pachiyero chidiki pane polyolefin mafirimu.Zvimwe zvinoshandiswa zvinosanganisira mabhegi, liners, sleeving yebhodhoro, adhesive tepi inotsigira, mavara, mabhegi eropa uye IV mabhegi.Inowanzo kuvharidzirwa nePVDC kana zvivakwa zvakavandudzwa zvekudzivirira hunyoro zvichidikanwa.

FDA yakatenderwa PVC isarudzo yakanaka kurongedza nyama tsvuku nyoro nekuti inopindika, zvichireva kuti inongokwana mweya weokisijeni kuti uchengetedze zvigadzirwa zvenyama zvinyoro uye kuchengetedza ruvara rwayo rutsvuku rwakajeka.Kana kujeka kwakakosha, PVC inowanzoshandiswa.

Polyvinyl Chloride, inonzi PVC, ndeimwe yemhando dzepurasitiki dzakagadzirwa, iyo yazvino inobuda ndeyechipiri kune polyethylene.Polyvinyl chloride yakashandiswa zvakanyanya muindasitiri, kurima uye hupenyu hwezuva nezuva.Polyvinyl chloride inhengo yepolymer yakagadzirwa nevinyl chloride.Inonzi thermoplastic.Upfu huchena kana huyero hwakareruka.Inonyungudika mumaketone, esters, tetrahydrofurans uye mahydrocarboni ane chlorinated.Excellent chemical resistance.Kusagadzikana kwemafuta uye kushomeka kwechiedza, kupfuura 100 ℃ kana kuratidzwa kwenguva refu kuchiedza chezuva kwakatanga kuora hydrogen chloride, kugadzira mapurasitiki kunoda kuwedzera stabilizer.Kuiswa kwemagetsi kwakanaka, hakupise.

Giredhi S-700 inonyanya kushandiswa kugadzira maflakes akajeka, uye inogona kudzvanywa kune yakaoma kana semi-yakaoma chidimbu kana pepa repasuru, zvinhu zvepasi, firimu rakaoma rekugadzira (yepepa rekupeta zvihwitsi kana firimu rekutakura fodya), nezvimwe. Inogona. wedzerawo kune yakaoma kana semi-yakaoma chidimbu, shizha, kana isina kurongeka bhaa yepasuru.Kana kuti inogona kubaiwa kuti igadzire majoini, mavharuvhu, zvikamu zvemagetsi, auto accessories uye midziyo.
