Kuyamba kwa ulusi wa Uhmwpe

Ultra - kulemera kwa ma polyethylene (ulusi wa UHMWP) umadziwika kuti ndi mphamvu zawo, zopepuka, komanso kugwiritsa ntchito mankhwala abwino. Mafuta awa amagwiritsidwa ntchito kwambiri pantchito kutetezedwa ndi zipatala. Mafuta a UHMWPWE amasunga nyonga yayikulu komanso machenjerero ochepa, kuwapangitsa kukhala abwino kwa onse ogwiritsa ntchito mafakitale ndi ogula.

Makhalidwe a UHMWPWP

Mafuta a UHMWPWE amadzitamandira kwambiri pakati pa 3 mpaka 6 miliyoni G / Mol, omwe amathandizira kuti awonjezere zachilengedwe. Zithunzizi zimawonetsa kuchepa kwamphamvu (0.93 mpaka 0.97 g / cm³), mphamvu zazikulu kwambiri, komanso zolimbana zazikulumiza, komanso zotsutsana zazikulu, zimawapangitsa kuti azikonda zokongoletsa zina.

Zopangira zopangira za UHMWPE

Chinsinsi cha kupanga kwa okwera - ulusi wa UHMWPOWPE NTHAWI ZABWINO ZABWINO KWAMBIRI NDIPONSO ZOSAVUTA. Zogulitsa zoyambirira ndi polyethylene ufa wokhala ndi kulemera kwakukulu kwambiri, kuchokera ku Othandizira Odalirika kuti atsimikizire kuti ali ndi mwayi wotsimikizira kuti ndi magwiridwe antchito. Zowonjezera ngati antioxidants ndi okhazikika a UV nthawi zina amasakanikirana ndi kukhazikika.

Polyethylene ufa ufa

Ufa wa polyethylene wogwiritsidwa ntchito ayenera kukhala ndi kulemera kwa maselo 3 miliyoni G / Mol kuti akwaniritse zomwe mukufuna. Kukula kwa tinthu tating'onoting'ono ndi chiyero choyera kumatha kukhudzanso njira yopumira ndi mawonekedwe omaliza a ulusi.

Kupanga kwa polymerization ku UHMWPWPWPWEP

Polymerization ndi njira yovuta kwambiri pakupanga uhmwpe, monga zimatsimikizira kulemera kwa maselo ndi mawonekedwe a fiber. Njira zapamwamba za polymerization zimagwiritsidwa ntchito kuti apange kulemera kwamphamvu kwa polyethylene moldely.

Njira Zapamwamba za Polymerization

Njira zodziwika bwino zimaphatikizapo Zegler - Natta ndi Sanlocene CATALSIS. Njira izi zimathandizira kuwongolera kutalika kwa polymer utoto, zomwe zimapangitsa uhmwpe ndi mphamvu zapamwamba kwambiri.

Maukadaulo a Gel

• Zoyambira za gel opindika
• Ubwino wa gel opindika za uhmwpe

Kupindika kwa gel ndi njira yapadera yomwe imagwiritsidwa ntchito kutulutsa ulusi wa Uhmwpe, kuonetsetsa kuti asunga zokongola. Munjira iyi, polymer amasungunuka mu solumu yoyenerera kuti apange gelve - monga yankho, omwe amathekera kudzera mu spinneret kuti apange ulusi.

Magawo mu gel opindika

Kukhazikika kwa yankho la polymer, onjezerani kutentha, ndipo jambulani kuchuluka kwake ndikofunikira magawo ofunikira omwe amathandizira kuti katundu womaliza a fiber. Nthawi zambiri, chiwerengero cha mawu a 20: 1 chimagwiritsidwa ntchito kukwaniritsa mphamvu zabwino kwambiri komanso zopanda mphamvu.

Zojambula ndi njira zotambasuka

Akasaka ulusi wa Uhmwpe ndi gel swun, amajambula pojambula ndi kutambasula. Izi zimathandizanso kusinthika kwa maunyolo a polymer, kukulitsa mphamvu yakulima komanso kuuma.

Mikhalidwe yotambalala

Zithunzizi zimatambasulidwa pamatenthedwe a 130 ° C ndi 150 ° C. Chiwerengero chotambasula, nthawi zambiri chopitilira 30: 1, chikugwirizana ndi maunyolo a masenteli kuti apititse magwiridwe antchito.

Njira zokhazikika

Kukhazikika kwa mafuta ndikofunikira kuonetsetsa kuti zifaniziro zokumana ndi kutentha mitundu popanda kuwonongeka. Izi zimaphatikizapo kuwongolera kuti mupumule kutsitsa nkhawa zamkati mu ulusi.

Kufunikira kwa chithandizo kutentha

Kutentha kumachitika pamatenthedwe ozungulira 135 ° C. Kutalika kwa nthawi ndi kutentha kuyenera kulamulidwa mosamala kuti musunge zinthu zabwino kwambiri.

Pamtunda ndi zokutira

Mankhwala okumba kapena zokutira zitha kugwiritsidwa ntchito ku ulusi wa UHMWP kuti uwonjezere kulumikizana kwawo kophatikizika ndikusintha kufooka.

Njira Zogwirizanitsa Zogwirizana

Njira zodziwika bwino zimaphatikizapo chithandizo chamankhwala cha plasma ndi mankhwala opaka mankhwala. Mankhwalawa amalimbikitsa chotsatira cha ulusi wa uhmwpe ku zinthu zina, kukulitsa gawo lawo.

Kuwongolera kwabwino mu UHMWPEPE

Kusungabe Zogwirizana Kwambiri Njira yonse ya UHMWpe imatsimikizira kuti ulusi amakwaniritsa zofunikira zamakampani ndi zomwe makasitomala akuyembekezera.

Chitsimikizo Chotsimikizika

Ma protocols amaphatikizapo kuyezetsa kwa Tansile, miyeso ya modulus, ndi mawonekedwe apamwamba. Kuyesa kwa Batch nthawi zonse motsutsana ndi zizindikiro zamakampani kumayambitsa kusinthasintha komanso kudalirika.

Maganizo a chilengedwe ndi chitetezo

Kupanga ulusi wa UHMWPE kumaphatikizapo kutsatira miyezo yachilengedwe ndi chitetezo kuti muchepetse kusintha ndikudzitchinjiriza.

Kutsatira malamulo

Opanga amatsatira malamulo apadziko lonse lapansi ndi malamulo azachilengedwe. Kugwiritsa ntchito njira zofufuzira zobwezeretsanso komanso kuwononga zinyalala kumachepetsa mawonekedwe a nkhalango.

Zochita zamtsogolo mu UHMWPE

Zatsopano zimapitilira kuyendetsa bwino popanga ndikugwiritsa ntchito ulusi wa Uhmwpe. Zinthu zomwe zikuchitika zimayang'ana pakuwonjezera magwiridwe antchito ndi chilengedwe.

Kupititsa patsogolo kwaukadaulo

Kuchitika mtsogolo kumatha kuphatikizira kuphatikiza kwa nanotechnology kuti apititsetse mphamvu - to radio younikira ndi kukhazikika kwa kupanga fiber.

Changqingteng amapereka mayankho

Cha Changqingteng amadzipereka popereka njira zatsopano zopangira ndikugwiritsa ntchito ulusi wa Uhmwpe. Monga othandizira otsogola ku China, timatsimikizira njira zathu zopanga zimakwaniritsa miyezo yapamwamba kwambiri komanso yokhazikika. Gulu lathu la akatswiri limadzipereka kuti lizipititsidwa ndi kukula, kuonetsetsa kuti zinthu zathu zili patsogolo pa ntchito za mafakitale. Mwa kusamalira nafe, makasitomala amapeza zinthu zomwe zimapereka zabwino mu magwiridwe ndi kudalirika, zogwirizana ndi zofunikira zawo.
