Sib txawv ntawm peb hom PE yas
Polyethylene, luv rau PE, feem ntau siv hauv peb pawg: LDPE HDPE LLDPE. Lub monomers ntawm peb hom polyethylene yog tib yam, tab sis cov txheej txheem cov txheej txheem siv los coj los ua ke cov polyethylenes no sib txawv. Cov yam ntxwv ntawm peb hom ntaub ntawv zoo sib txawv me ntsis.0010010 nbsp;
LDPE, luv luv rau ntom ntom polyethylene, scientific lub npe ntawm qhov ntom ntom polyethylene siab polyethylene. Polyethylene yog cov khoom siv translucent dawb siv nrog lub teeb ntom ntom, muag muag thiab tawv, me ntsis elongated, tsis muaj tshuaj lom, tsis muaj ntxhiab kev sib xyaw ua ke thiab cov nplaim taws. Nws tuaj yeem txuas mus hlawv tom qab hluav taws. Cov nplaim yog daj rau saum thiab xiav nyob hauv qab. Thaum hlawv, nws yuav yaj, nrog kua poob tawm, tsis muaj pa taws tawm hauv, thiab tawm qhov ua tsw ntawm hlawv roj.

Siv: rau extrusion ntim zaj duab xis, zaj duab xis ntim, thiab hose; rau kev txhaj tshuaj molding ntawm qib qis cov khoom lag luam thiab lub plhaub; rau extrusion tshuab-tshuab moulding ntim.
HDPE, luv rau qhov siab ntom ntom polyethylene, nws lub npe scientific yog qhov siab ntom ntom polyethylene tsis tshua muaj siab polyethylene. HDPE yog opaque dawb ciab-zoo li cov khoom siv nrog lub teeb sib sib zog nqus, muag muag thiab tawv, tab sis me ntsis nyuaj thiab ntev dua li LDPE. Cov mob tsis muaj tshuaj lom, tsis qab, nplaim taws ua kom kub nyhiab, tom qab hluav taws tuaj yeem hlawv txuas ntxiv, nplaim taws yog daj nyob rau saum toj, xiav rau hauv qab. Thaum hlawv, nws yuav yaj, nrog kua poob tawm, tsis muaj pa taws tawm hauv, thiab tawm qhov ua tsw ntawm hlawv roj.
Qhov zoo: acid thiab alkali tsis kam, organic kuab kuj, zoo hluav taws xob rwb thaiv tsev, tsis tshua muaj kub kuj tseem tuaj yeem tswj tau qee yam ntawm kev ua kom tawv, tawv tawv, lub zog tawv thiab lwm yam lub zog yog siab dua LDPE thiab ze rau PP, nruj dua PP, tab sis cov npoo tiav yog tsis zoo li PP.0010010 nbsp;
Kev tsis zoo: cov khoom tsis zoo lub cev, lub tshuab huab cua tsis zoo, ua kom tsis yooj yim, laus yooj yim, yooj yim brittleness, brittleness qis dua PP, yooj yim tawg siab, tsis tshua muaj cov tawv tawv, yooj yim kos, tsis yooj yim luam ntawv, tsis-plating, npub saum npoo.
Siv: Siv rau extruding ntim zaj duab xis, hlua, lub hnab ntim khoom, hnab nuv ntses, dej yeeb nkab; siv rau kev txhaj tshuaj molding ntawm cov khoom lag luam qis qis thiab lub plhaub, cov khoom thauj tsis-thauj cov kabmob, lub thawv roj hmab, lub thawv tig; siv rau kev rho tawm tshuab-ntim cov thawv ntim khoom thiab lub raj mis ntawm cov khoom lag luam.
Qhov zoo: acid thiab alkali tsis kam, organic kuab kuj, zoo hluav taws xob rwb thaiv tsev, tsis tshua muaj kub kuj tseem tuaj yeem tswj tau qee yam ntawm kev ua kom tawv, tawv tawv, lub zog tawv, kev ua kom nruj thiab lwm yam muaj zog dua li LDPE, tab sis qis dua HDPE, LLDPE puncture resistance yog qhov zoo tshaj plaws. Kua muag tsis kam, tshwj xeeb tshaj yog tsim rau kev tsim cov zaj duab xis nyias, tab sis muaj zog dua LDPE.
Qhov tsis zoo: cov khoom tsis zoo lub cev, lub tshuab huab cua tsis zoo, ua rau lub cev tsis yooj yim, kev laus yooj yim, yooj yim brittleness, brittleness qis dua PP. Yooj yim tawg yooj yim, tsis tshua muaj cov tawv tawv, kos yooj yim, luam ntawv nyuaj. Tsis tuaj yeem ua electroplated, qhov saum npoo yuav ci.

Siv: Siv rau extruding ntim zaj duab xis, daim kab xev, cable, tsim zaj duab xis, tseem hu ua ntawv zoo li zaj duab xis; siv rau kev txhaj tshuaj molding ntawm cov khoom lag luam qis thiab cov plhaub; siv rau extruding tshuab-tshuab moulding thawv, hollow khoom fwj.
Qhov sib txawv ntawm LDPE, HDPE thiab LLDPE yog qhov tseem ceeb hauv ntom ntom, uas ua rau cov khoom sib txawv hauv cov cuab yeej muaj zog. Ib qho yog nruj heev thiab lwm qhov yog hloov tau. Qhov sib txawv ntawm LLDPE thiab LDPE yog qhov tseem ceeb hauv cov qauv molecular. LLDPE muaj ntau cov ceg sib txuas. Yog li ntawd, cov khoom siv no yog hloov tau thiab xeb.
