Chii PU mavhiri vari? Ndezvipi zvakanakira Pu kumativi ikoko?
Chii PU mavhiri vari? Chii chinoratidza Pu kumativi ikoko?
Urethane aizivikanwa PU vhiri, rabha chitubu, inonzi: Poly urethane kana isocyanate polymer. PU iri vhiri Zekaria pakati mapurasitiki uye elastomeric rabha, iyo yakanaka mune uchitikurudzira kuita yaingowanikwa misi mupurasitiki uye rabha hazvisi kuwanikwa.
Ndehupi hunhu pu kumativi ikoko?
PU elastomers vhiri zvinosanganisira abrasion, kemikari nemishonga, mukuru simba, mukuru elasticity, pasi kumanikidzwa nemishonga, abrasion, kuvhunduka Absorção de Água uye simba, misodzi nemishonga, nemwaranzi nemishonga, yakakwirira mutoro uye kuvhunduka Absorção de Água zvivako, zvakadai zvakanaka. PU vhiri pamwe akasiyana-siyana zvakaoma scale, kubva Shaw A10-100.
Kune kare mhiri Shaw A100 uye pamusoro zvigadzirwa. Uyezve, PU vhiri dzine ndisingafungiri rokutora unongotaura nani kunogona damping piro ndiro, tinzwe nemishonga pane simbi zvitubu, kwete kuti vatadzire chakuvhuvhu. maitiro aya PU mavhiri, casters dzakakodzera chaizvo zvinhu.
The nzira kugadzira PU vhiri
Wheel PU elastomers anogona kutorwa sezvo mukuru chinangwa rabha mastication, nokusanganisa, vulcanization Kuumbwa kwacho (kureva MPU); PU vhiri zvinogona kuitwa imvura rabha, spraying kana achidzinga kuumbwa vachikanda, Centrifugal Kuumbwa (kureva CPU); PU kumativi pellets uyewo kuitwa, sezvinoitwa vanhuwo mapurasitiki, jekiseni, extrusion, calendering, muridze kuumbwa nezvimwe kuumbwa kwacho (kureva CPU). Kuumbwa kana jekiseni rakaumbwa nyaya, sokukumbira zvakaoma scale, zviri kugonawo kutema, kukuya, kuchera nezvimwe machine. Processing zvakasiyana-siyana, kuti applicability pakati PU elastomers zvakajairika, kushandiswa muchikwata yave kuwedzera.
Detailed kushandisa zvinhu PU zvinhu kumativi
PU caster vhiri harisi chete rakanaka, nyoro furo chairarirwa Zvichienderana PU zvinhu-zvakadai dzakakwirira macheya, kangas, nepanhovo, nyoro polyurethane furo chinhu chinoshamisira chaizvo rukukwe zvinhu, kunonyanyisa kushandisa bonde riri nyoro furo chipimo chemushonga chikamu, riri kudziya uye yakanaka chaizvo.
Fabric rinoumba zvinhu-pamafudzi Mapedhi, bhurezha chipanje, donje ikanyanya; matoyi.
PU furo Hazvichinji-chinji PU
PU furo vhiri refrigerated midziyo-zvakadai sefiriji, mafiriza, kutonhora kuchengetwa, kutonhora okuchengetera dzimba, nezvimwewo, vanachandagwinyira polyurethane furo ndiyo tarenda Refrigeration midziyo kuputira zvinhu, kushandiswa maererano vakawanda;
