M'malo omwe akukula mwachangu polima polima, Thermoplastic elastomers (TPEs) zatuluka ngati gulu losunthika komanso lofunikira la zida, kuletsa kusiyana pakati pa mapulasitiki olimba ndi mphira zotanuka. Kuphatikiza kwawo kwapadera kwa thermoplastic processability ndi kusinthasintha kwa elastomeric kwawapanga kukhala zinthu zosankhika m'mafakitale osiyanasiyana., kuyambira zamagalimoto ndi zamagetsi kupita ku zomanga ndi zogula. Zhuoyue, mtsogoleri waukadaulo wa extrusion, idaperekedwa kuti ipereke zida zamakono zozungulira zozungulira ziwiri zomwe zimapangidwa makamaka kuti ziphatikizire ndi kukonza ma TPE., kuphatikiza TPE/SBS/TPU/TPR/TPV ndi zina zophatikizika zina. Ndi kumvetsetsa kwakukulu kwa katundu wa TPE ndi zosowa zamakampani ogwiritsira ntchito, Mndandanda wa Zhuoyue extruder umapereka ntchito zosayerekezeka, kuchita bwino, ndi kudalirika, kupatsa mphamvu opanga kuti atsegule kuthekera konse kwa zida zapamwambazi.

1. Chidule cha Thermoplastic Elastomers (TPEs)

Thermoplastic Elastomers (TPEs), Nthawi zina amatchedwa Thermoplastic Rubbers (Zithunzi za TPR), ndi mitundu yosiyanasiyana ya zida zomwe zimawonetsa mawonekedwe apawiri a thermoplastics ndi elastomers. Mosiyana ndi mphira zachikhalidwe zolumikizirana, zomwe sizisungunuka ndipo sizisungunuka zikangochiritsidwa, Ma TPE amatha kusungunuka ndikusinthidwanso pogwiritsa ntchito njira zokhazikika za thermoplastic monga extrusion, jekeseni akamaumba, ndi kuwombera mphepo, ndikukhalabe bwino zotanuka kuchira ndi kusinthasintha kutentha firiji. Uwiri wapadera umenewu umachokera ku mamolekyu awo: Ma TPE nthawi zambiri amakhala ma copolymers (ma polima opangidwa ndi mayunitsi awiri kapena angapo osiyana) kapena kusakanikirana kwakuthupi kwa chigawo cha pulasitiki ndi chigawo cha rabara, kumene gawo la pulasitiki limapanga matrix opitirira omwe amafewetsa ndikuyenda pamene akutenthedwa, ndi gawo la mphira limapereka elasticity ndi kupirira.

Ubwino waukulu wa ma TPE kuposa ma mphira wamba ndi mapulasitiki apangitsa kuti atengeke kwambiri pakupanga zamakono.. Ubwinowu umaphatikizapo: kwambiri processability (kulola kupanga kwachangu komanso magawo ovuta a geometri), recyclability (kuchepetsa zinyalala zakuthupi ndi chilengedwe), kukana mankhwala abwino, wapamwamba makina katundu (monga mphamvu yolimba, elongation panthawi yopuma, ndi kukana abrasion), ndi luso lakuda, zopangidwa, kapena kusinthidwa kuti zikwaniritse zofunikira zinazake. Kuphatikiza apo, Ma TPE amapulumutsa ndalama popanga chifukwa cha nthawi yayifupi yozungulira, kuchepetsa kugwiritsa ntchito mphamvu, ndi kuthetsa njira zochiritsira zomwe zimafunikira mphira wamba.

Monga kufunika opepuka, cholimba, ndi zipangizo zokhazikika zikupitiriza kukula, Ma TPE akhala ofunika kwambiri m'mafakitale monga zamagalimoto (pofuna kuchepetsa komanso kuchepetsa phokoso), zamagetsi (kwa zigawo zosinthika komanso zolimba), ndi katundu wogula (kwa zinthu zabwino komanso ergonomic). Kuti mugwiritse ntchito bwino ma TPEs, opanga amafuna zida zopangira zomwe zimatha kuthana ndi zovuta zapadera zazinthu izi, kuphatikizapo kumva kwawo kutentha, shear mlingo, ndi kusakaniza kufanana. Zhuoyue's co-rotal parallel-screw extruder adapangidwa kuti athetse mavutowa., kuonetsetsa kusasinthasintha, ma TPE apamwamba kwambiri omwe amagwira ntchito bwino.

2. Magulu Asanu ndi Amodzi Azambiri a Ma TPE Zamalonda

Ma TPE azamalonda amagawidwa m'magulu asanu ndi limodzi kutengera momwe amapangira mankhwala, kapangidwe ka maselo, ndi mawonekedwe a ntchito. Gulu lirilonse liri ndi zinthu zapadera zomwe zimapangitsa kuti zikhale zoyenera kwa mapulogalamu apadera, ndi Zhuoyue's extruder mndandanda amapangidwa kuti athe kusamalira zofunikira zamtundu uliwonse, kuonetsetsa zotsatira zabwino kwambiri zophatikizira. Pansipa pali tsatanetsatane wa gulu lililonse, kuphatikizapo kapangidwe kawo, katundu, ndi ntchito wamba:

2.1 Styrenic Block Copolymers (TPS, TPE-s)

Styrenic Block Copolymers (TPS), amadziwikanso kuti TPE-s, ndi gulu logwiritsidwa ntchito kwambiri komanso losunthika la ma TPE, kuwerengera gawo lalikulu pamsika wapadziko lonse wa TPE. Amapangidwa ndi midadada yosinthika ya styrene (cholimba thermoplastic monomer) ndi diene (flexible elastomeric monomer), kawirikawiri butadiene, isoprene, kapena zotumphukira zawo za hydrogenated. Mitundu yodziwika bwino ya TPS ndi Styrene-Butadiene-Styrene (SBS), Styrene-Isoprene-Styrene (SIS), Hydrogenated SBS (Mtengo wa SEBS), ndi Hydrogenated SIS (SEPS).

Mapangidwe apadera a block a TPS amawapatsa mawonekedwe awo: zitsulo za styrene zimakhala zolimba, magalasi madera kutentha firiji kuti amakhala ngati thupi cross-links, kupereka mphamvu zamakina ndi kukhazikika kwa mawonekedwe, pomwe midadada ya diene imakhala yofewa, madera a rubbery omwe amapereka elasticity ndi kusinthasintha. Pamene usavutike mtima pamwamba galasi kusintha kutentha kwa styrene midadada (pafupifupi pafupifupi 100 ° C), madera olimba amafewetsa ndikuyenda, kulola kuti zinthuzo zisinthidwe ngati thermoplastic; itazizidwa, madera ovuta apanganso, kubwezeretsanso mphamvu za elastomeric.

Zofunikira za TPS zimaphatikizapo kusinthasintha kwabwino, mphamvu yabwino yolimbikira, otsika osalimba, wapamwamba processability, ndi kuyanjana ndi mitundu yosiyanasiyana ya zowonjezera (monga plasticizers, fillers, ndi stabilizers). Amawonetsanso kukana bwino kwa madzi, mafuta, ndi mankhwala, ngakhale hydrogenated TPS (Mtengo wa SEBS, SEPS) perekani bwino kukana kwa okosijeni ndi kutentha poyerekeza ndi mitundu yopanda hydrogenated (SBS, SIS).

Ntchito zofananira za TPS zikuphatikiza: zigawo zamagalimoto (nyengo, zisindikizo pakhomo, dashboard trim, ndi shock absorbers), katundu wa ogula (zidole, gwira, zogwira, ndi nsapato), zida zamankhwala (machubu a catheter, jekeseni wa syringe, ndi zisindikizo zachipatala), ndi zomatira ndi zosindikizira (zomatira zotentha zosungunuka, zomatira zotengera kuthamanga). Zhuoyue's extruders amakongoletsedwa ndi TPS processing, ndi kuwongolera bwino kwa kutentha komanso kuthekera kosakanikirana koyenera kuwonetsetsa kubalalitsidwa kofananira kwa zowonjezera ndi zinthu zofananira.

2.2 Thermoplastic Polyolefin Elastomers (TPO, TPE-o)

Thermoplastic Polyolefin Elastomers (TPO), kapena TPE-o, ndi zosakanikirana zakuthupi za polyolefin (kawirikawiri polypropylene, PP) ndi elastomer (kawirikawiri ethylene-propylene-diene monomer, Chithunzi cha EPDM). Mosiyana ndi TPS, zomwe ndi copolymers, Ma TPO ndi osakanikirana mosiyanasiyana pomwe polyolefin imapanga matrix osalekeza ndipo elastomer imapanga madera osiyanasiyana a rubbery.. Makhalidwe a TPO amatha kusinthidwa posintha chiŵerengero cha polyolefin ku elastomer, komanso mtundu ndi kuchuluka kwa zowonjezera (monga fillers, antioxidants, ndi UV stabilizers).

TPOs amapereka kuphatikiza kwapadera kwa katundu, kuphatikizapo kukana kwambiri nyengo, kukana mankhwala abwino (makamaka kwa ma asidi, maziko, ndi mowa), otsika osalimba, mphamvu yamphamvu kwambiri, ndi processability wabwino. Zimakhalanso zotsika mtengo poyerekeza ndi magulu ena a TPE, kuwapanga kukhala chisankho chodziwika pamapulogalamu akuluakulu. Kuphatikiza apo, Ma TPO amatha kubwezeretsedwanso ndipo amatha kusakanikirana ndi ma polyolefin ena kuti apititse patsogolo magwiridwe antchito kapena kuchepetsa ndalama.

Chimodzi mwazabwino zazikulu za TPOs ndikukana kwawo ku radiation ya UV ndi ozoni, zomwe zimawapangitsa kukhala abwino kwa ntchito zakunja. Amakhalanso ndi kukhazikika kwabwino kwa kutentha, pogwiritsa ntchito mosalekeza kutentha kuyambira -40°C mpaka 120°C, kutengera kapangidwe. Ma TPO amapezeka mumitundu yosiyanasiyana yazovuta, kuchokera kufewa ndi kusinthasintha (Shore A 50) ku zolimba (Shore D 70), kuwapanga kukhala oyenera kugwiritsa ntchito zosiyanasiyana.

Zomwe zimagwiritsidwa ntchito ndi TPOs zikuphatikiza: zigawo zamagalimoto (zophimba zazikulu, zotetezera, mapanelo a zitseko, ndi zishango zakunsi), zomangira (denga nembanemba, zisindikizo za mawindo, ndi decking), katundu wa ogula (zipangizo za udzu ndi munda, zida zamasewera, ndi katundu), ndi zigawo za mafakitale (hoses, gaskets, ndi zisindikizo). Zhuoyue extruder ali ndi zida zapadera zopangira zomangira ndi makina owongolera kutentha kuti zitsimikizire kusakanikirana kofanana kwa gawo la polyolefin ndi elastomer., kuletsa kulekanitsa gawo ndikuwonetsetsa kuti zinthu zikuyenda bwino.
