YIHOO PA (polyamide) polymerization & zosintha zowonjezera
Polyamide (yotchedwanso PA kapena Nylon) ndi mawu ofananirako ndi utomoni wa thermoplastic, wokhala ndi gulu lama amide mobwerezabwereza pamakina akulu am'magulu. PA imaphatikizapo aliphatic PA, aliphatic - onunkhira PA ndi onunkhira PA, momwe aliphatic PA, yochokera ku kuchuluka kwa maatomu a kaboni mu monomer wopanga, ili ndi mitundu yambiri, kuthekera kwambiri ndikugwiritsa ntchito kwambiri.
Ndi miniaturization yamagalimoto, magwiridwe antchito apamwamba azida zamagetsi ndi zamagetsi, komanso kuthamangitsa kwa njira zopepuka zamagetsi, kufunika kwa nayiloni kudzakulirakulira. Zofooka za nayiloni ndizofunikanso pakulepheretsa kagwiritsidwe kake, makamaka pa PA6 ndi PA66, poyerekeza ndi mitundu ya PA46, PA12, ili ndi mwayi wokwera mtengo, ngakhale magwiridwe ena sangakwaniritse zofunikira pakupanga mafakitale ofanana.

YIHOO PU (polyurethane) zowonjezera thovu
Pulasitiki ya thovu ndi imodzi mwazinthu zazikulu kwambiri zopangidwa ndi polyurethane, zomwe zimakhala ndi porosity, chifukwa chake kuchuluka kwake kumakhala kochepa, ndipo mphamvu yake ndiyapamwamba. Malinga ndi zipangizo zosiyanasiyana zopangira ndi chilinganizo, zikhoza kupangidwa kukhala zofewa, theka-okhwima ndi okhwima polyurethane thovu pulasitiki etc.
Chithovu cha PU chimagwiritsidwa ntchito kwambiri, pafupifupi kulowerera m'magulu onse azachuma, makamaka mipando, zofunda, mayendedwe, kuzizira, zomangamanga, kutchinjiriza ndi ntchito zina zambiri.

Zowonjezera za YIHOO PC (Polycarbonate)
Polycarbonate (PC) ndi polima yomwe ili ndi gulu la carbonate munthawi yamagulu. Malinga ndi kapangidwe ka gulu la ester, amatha kugawidwa mu aliphatic, onunkhira, aliphatic - onunkhira ndi mitundu ina. Makhalidwe otsika a aliphatic ndi aliphatic onunkhira polycarbonate amachepetsa momwe amagwiritsira ntchito mapulasitiki amisiri. Mafuta onunkhira okhaokha a polycarbonate ndi omwe amapangidwa mwaluso. Chifukwa chakudziwika kwa kapangidwe ka polycarbonate, PC yakhala pulasitiki yaukadaulo yomwe ikukula kwambiri pakati pa mapulasitiki asanu amisiri.
PC imagonjetsedwa ndi kuwala kwa ultraviolet, alkali yamphamvu, ndi kukanda. Amasandulika wachikaso ndikuwonekera kwakanthawi kwa ultraviolet. Chifukwa chake, kufunikira kwa zowonjezera zosinthidwa ndikofunikira.

Zowonjezera za YIHOO TPU elastomer (Thermoplastic polyurethane elastomer)
Thermoplastic polyurethane elastomer (TPU), yomwe imagwiritsa ntchito bwino kwambiri komanso imagwiritsidwa ntchito kwambiri, yakhala imodzi mwazinthu zofunikira kwambiri za thermoplastic elastomer, zomwe mamolekyulu ake amakhala ofanana kwambiri osalumikiza mankhwala.
Pali maulalo ambiri opangidwa ndimalumikizidwe a haidrojeni pakati pama mzere unyolo wambiri wa polyurethane, womwe umalimbitsa ma morpholoji awo, potero umapereka zinthu zambiri zabwino, monga modulus, mphamvu yayikulu, kukana kwabwino kwambiri, kukana mankhwala, kukana kwa hydrolysis, kukwera otsika kutentha kukana ndi nkhungu kukana. Izi ndizabwino kwambiri zomwe zimapangitsa kuti thermoplastic polyurethane igwiritsidwe ntchito m'malo ambiri monga nsapato, chingwe, zovala, galimoto, mankhwala ndi thanzi, chitoliro, kanema ndi pepala.

YIHOO Low VOC magalimoto chepetsa zowonjezera
M'zaka zaposachedwa, ndikukhazikitsa malamulo oyendetsa mlengalenga mgalimoto, mawonekedwe oyendetsa magalimoto ndi VOC (osakhazikika a Organic Compounds) akhala gawo lofunikira pakuwunika magalimoto. VOC ndiye lamulo lazinthu zamagulu, makamaka limatanthawuza kanyumba wamagalimoto ndi zonyamula katundu kapena zida zamagulu, makamaka ma benzene, ma aldehydes ndi ketoni ndi undecane, butyl acetate, phthalates ndi zina zotero.
Kuchuluka kwa VOC m'galimoto kukafika pamlingo wina, kumadzetsa zizindikilo monga kupweteka mutu, nseru, kusanza ndi kutopa, komanso kupweteketsa mtima ndi kukomoka zikavuta. Zingawononge chiwindi, impso, ubongo ndi ubongo, zomwe zimapangitsa kuti anthu asamaiwale kukumbukira komanso zotsatira zina zoyipa, zomwe zimawopseza thanzi la munthu.
