Chigadzirwa molecular chimiro:
Kemikari uye zvimiro zvemuviri zvinokanganiswa zvakanyanya nekuwedzera density, iyo inokanganiswa nechimiro uye spacing yemamorekuru cheni. Low-density zvinhu zvine matavi akanyanya uye akapatsanurwa cheni, nepo yakakwirira-density zvinhu zvine cheni dzakati twasu uye dzakanyatsoenderana. Low-density polyethylene (0.926–0.9409 g/cm3) inonyungudika muorganic solvents patembiricha inodarika 200°F. Haina kunyungudika pakupisa kwekamuri. High-density polyethylene (0.041–0.965 g/cm3) is hydrophobic, permeable to gas, uye ine high magetsi resistivity.
Low molecular uremu polyethylenes ane yakanakisa magetsi kuramba uye kuramba mvura uye kune akawanda makemikari. Medium molecular weight polymers iwakisi inosanganiswa neparafini wakisi, uye polyethylene mapolima ane huremu hwemamorekuru akakwira kupfuura zviuru gumi ndiwo anojairika akasimba uye akasimba resin anochinjika kana kuoma. Nekusiyanisa iyo inokonzeresa uye nzira dzepolymerization, zvivakwa zvakaita se density, crystallinity, molecular weight, uye polydispersity zvinogona kudzorwa pamusoro pehupamhi. Mapolymer ane density kubva paanenge 0.910 kusvika 0.925 g/cm3 ari low-density polyethylenes; avo vane density kubva 0.926 kusvika 0.940 g/cm3 vari medium-density polyethylenes; uye avo vane density kubva 0.941 kusvika 0.965 g/cm3 uye yakakwirira vari high-density polyethylenes.
Polyethylene (PE) inonzi thermoplastic polymer inoumbwa nemacheni akareba ehydrocarbon. PE inoshandiswa mune akati wandei maapplication anosanganisira anochinjika firimu kurongedza anogadzirwa neyakavhuvhuta firimu maitiro. Polyethylene inoshandiswa kudzora viscosity, kumiswa zvivakwa, uye kugadzikana kwakawanda mukuumbwa kwezvizoro. Mashandisirwo akajairika aisanganisira akasarudzika jekiseni akaumbwa zvikamu, muminda iyi Polyethylene ine dzakasiyana siyana dzekushandisa:
Jekiseni uye kuvhuvhuta matoyi akaumbwa, midziyo yemumba nemavharo.
Majekiseni akaumbwa zvigaro zvemotokari, mower parts uye mapails.
Majekiseni akaumbwa, matete-madziro midziyo uye midziyo yemumba.
Kupisa kunyunguduka kwekuputira kwebepa, kunowedzera muakaumbwa moldings, makenduru, mafuta-based ingi uye inopisa inonyunguduka inonamatira.
Inowedzera kune isina unsaturated polyesters, epoxides uye mamwe mapolymers kuti ape yakasarudzika zvimiro zveUHMWPE. Inoshandiswa muzvikamu zveindasitiri, machira uye kupfeka nzvimbo pa10-40 wt. %.
Mafirimu maapplication ane kudhirowa kwakanaka uye kuoma.
Mold kuburitsa inowedzera, lubricant mukugadzira rabha, extrusion uye calendering rubatsiro rwePVC uye kuparadzira rubatsiro rwekusimbisa ruvara.
Bearings, magiya, bushings nezvimwe zvikamu zvinofamba.
Laboratory tubing; mukugadzira prostheses; magetsi ekudzivirira; kurongedza zvinhu; kitchenware; tangi uye pombi linings; mapepa ekuputira; textile stiffeners.
polyethylene inoshandiswa kudzora viscosity, kuturika zvivakwa, uye kugadzikana kwakawanda mukuumbwa kwezvizoro. Inotorwa kubva mupetroleum gasi kana kupera simba kwedoro.
Chemwin inogona kupa huwandu hwakawanda hwemahydrocarbon akawanda uye makemikari zvinonyungudutsa kune vatengi vemaindasitiri.Izvi zvisati zvaitika, ndapota verenga zvinotevera ruzivo rwekuita bhizinesi nesu:
1. Chengetedzo
Chengetedzo ndiyo inonyanya kukosha kwatiri. Pamusoro pekupa vatengi ruzivo nezve mashandisiro akachengeteka uye ane hushamwari ezvigadzirwa zvedu, isu takazvipirawo kuona kuti njodzi dzekuchengetedza dzevashandi nemakondirakiti dzadzikiswa kuita shoma inonzwisisika uye inogoneka. Naizvozvo, isu tinoda kuti mutengi ave nechokwadi chekuti kurodha kwakakodzera uye kuchengetedza kuchengetedza zviyero zvinosangana tisati tasvitsa (ndapota tarisa kune HSSE appendix muhuwandu hwematemu uye mamiriro ekutengesa pazasi). Nyanzvi dzedu dzeHSSE dzinogona kupa gwara pane aya mazinga.
2. Delivery nzira
Vatengi vanogona kuraira uye kuendesa zvigadzirwa kubva kuchemwin, kana kuti vanogona kugamuchira zvigadzirwa kubva kune yedu kugadzira chirimwa. Nzira dziripo dzekutakura dzinosanganisira rori, njanji kana multimodal kutakura (zvakasiyana mamiriro anoshanda).
Panyaya yezvinodiwa nevatengi, tinogona kutsanangura zvinodikanwa zvemabhaji kana matangi uye kushandisa yakakosha kuchengetedza / kuongorora zviyero uye zvinodiwa.
3. Minimum order yakawanda
Kana iwe ukatenga zvigadzirwa kubva pawebhusaiti yedu, iyo yakaderera odha huwandu i30 matani.
4.Payment
Iyo yakajairika nzira yekubhadhara inobviswa zvakananga mukati memazuva makumi matatu kubva painvoice.
5. Delivery zvinyorwa
Mapepa anotevera anopiwa kune imwe neimwe yekutumira:
· Bill of Lading, CMR Waybill kana rimwe gwaro rekufambisa rakakodzera
· Sitifiketi Yekuongorora kana Conformity (kana zvichidikanwa)
· Zvinyorwa zvine chekuita neHSSE zvinoenderana nemitemo
· Zvinyorwa zvetsika zvinoenderana nemirairo (kana zvichidikanwa)
