Mawu OyambaPhazi la Polyethylenendi kutentha kwambiri

Mafuta a polyethylene, makamaka Ultra - Kulemera Kwakuthupi kwa Polyethylene (UHMWPWPE), imadziwika kuti mphamvu zawo - Ziwerengero zowonjezera, zida zowonongeka - zida zoopsa. Komabe, machitidwe awo awo pansi pamatenthedwe kwambiri ndi ofunikira kwambiri omwe angakhudze kudalirika kwawo komanso kulimba.

Kapangidwe kake ka polyethylene

Ma unyolo a UHMWPA amapangidwa ndi maunyolo ophatikizika kwambiri, kwambiri okhala ndi maunyolo okhala ndi crystality yayikulu. Kapangidwe kameneka kumapangitsa kuti awo akhale ochititsa chidwi, kuphatikizapo maluso a tunsile mpaka 4 GPA ndi kachulukidwe kakang'ono kuzungulira 0,97 g / cm3. Komabe, uja umphumphu ndi kulumikizananso zimapangitsa kuti ulusiwo utengeke ndi kuwonongeka kwa mafuta, komwe kumatha kusiya kukhulupirika kwawo.

Njira zochepetsera mafuta

Kutentha kwambiri kumatha kuyambitsa thermo - kuwonongeka kwa oxizath mu ma polyethylene. Njirayi imaphatikizapo mapangidwe a kaboni - Zithunzi zochokera ku C-C Bodersor Choder, zimapangitsa kuchepa kwa misa. Kukhalapo kwa ma radicals awa ndi chiletso chotsatira chotsatira chomwe chimakhudza mphamvu ya fiber.

Zosintha pamakina

Kuwonetsedwa kwa kutentha kwapamwamba kumatha kuchepetsa kwambiri magwiridwe antchito a polyethylene. Kukhala ndi mphamvu zambiri komanso nyonga za kumeta ung'ono zonse ziwiri zimachepera ngati kukalamba kwamafuta kumadutsa. Mwachitsanzo, zotsatira za kuyesedwa zikuwonetsa kuti ndikutentha kwambiri - Kuchulukitsa kutentha ndi nthawi, mphamvu yautu.

Ma crystology Morphlogy

Kutentha kwambiri kumasintha kumasinthidwe a Crystalogy ya ulusi wa polyethylene. Triver - Arle X - - Ray - ma sexs) amaulula kuwonjezeka kwa zigawo zakale, kufalitsa oxygen amasintha zinthu ndikukulitsa kuwonongeka kwa oxina. Kusintha kumeneku kumapangitsa kuti magetsi azikhala ndi misa ndi makina ofooka.

Kukhudzana kwa matenthedwe

Kukalamba kwa mafuta kumakhudza kutalika kwa nthawi yayitali - kukhazikika kwa ma polyethylene. Kukhalapo kwa zofooka ndi zosayera pokonzanso kumathandizira oxidation, kulimbikitsa chidule komanso kutaya mtima wamakina. Filid imatha kuchepa pakapita nthawi, zimakhudzanso kugwiritsa ntchito pogwiritsa ntchito monga kutetezedwa kophunzitsa.

Udindo wa Zosintha

Mikhalidwe yolondola, monga kutentha, nthawi yayitali, komanso kukakamizidwa nthawi yotentha - kukanikiza, ndikofunikira kuti musunge makina a Pulylenee. Kuyesedwa kumawonetsa kuti zojambula bwino kwambiri za nsalu zomwe sizimapezeka pa 130 ° C ndi kuchuluka kwa kuchuluka kwa anthu 595.43 MPA. Kusintha kwa kukakamizidwa kumatha kusinthana ndi kukangana kwakukulu.

Njira zoteteza ndi zowonjezera

Kukwaniritsa njira zotchinga, monga zofunda kapena zowonjezera, zimatha kukulitsa kukhazikika kwa ma polyethylene. Njira izi zimathandizira kuchepetsa kuchepa kwa thupi, kulola kuti ulusi kuti zisungidwenso mphamvu ndi kulimba pansi pa - kutentha. Ogulitsa ku China akupanga mwachangu materinoloji kuti apititse patsogolo magwiridwe ake.

Kufanizira ndi zinthu zina

Mafuta a polyethylene amapatsa mphamvu zabwino za mphamvu ndi kulemera poyerekeza ndi njira zina monga para - ulusi wa Aaramidi ndi chitsulo. Komabe, kukhazikika kwawo kwamafuta ndi kotsika, koyenera kwatsopano pokonza ndi kutetezedwa kutsimikizira kuti mpikisano. Zochita bwino popititsa patsogolo zinthu zakuthupi ndizofunikira kuti musunge utsogoleri wa msika.

Kafukufuku wamtsogolo ndi chitukuko

Kafukufuku wopitilira akuyang'ana kumvetsetsa kusintha kwa maselo a polyethylene pamatenthedwe otentha. Kupanga zida zapamwamba ndi matekinoloje apamtima kuti muchepetse thermo - Kuwonongeka kwa makuti oxida ndikofunikira kuti mukhalebe ndi mtima wosagawanika. Ogulitsa abwino ku China ali patsogolo pa kafukufukuyu, kuyesetsa kupereka mayankho apamwamba.

Changqingteng amapereka mayankho

Changqingteng imapereka njira zatsopano zothandizira kukhazikika kwa matenthedwe a polyethylene. Mukakonza mikhalidwe yoteteza ndikuphatikiza njira zotetezera zapamwamba, timatsimikiza kuti ulusi amasunga mphamvu zawo povuta. Kudzipereka kwathu kumatipangitsa kuti tizitsogolera pa malonda. Zotsatira zabwino, khulupiriraningqingerteng, wokondedwa wanu wodalira zakuthupi.
