Dab tsi yog Thermoplastic Powder Txheej

Ib qho thermoplastic hmoov txheej melts thiab ntws ntawm daim ntawv thov ntawm tshav kub, tab sis tseem muaj tib yam tshuaj muaj pes tsawg leeg thaum nws solidifies ntawm txias. Thermoplastic hmoov txheej yog raws li cov thermoplastic resins ntawm siab molecular hnyav. Cov khoom ntawm cov coatings no nyob ntawm cov yam ntxwv ntawm cov resin. Cov tawv thiab resistant resins zoo li yuav nyuaj, nrog rau kim, yuav tsum tau hauv av rau hauv cov khoom zoo heev uas tsim nyog rau daim ntawv thov tshuaj tsuag thiab fusing ntawm nyias zaj duab xis. Yog li ntawd, cov txheej txheem thermoplastic resin yog siv ntau dua li cov txheej txheem ua haujlwm ntawm ntau mils thickness thiab yog siv los ntawm cov txheej txheem ntawm cov ntaub ntawv fluidized txaj.

Cov piv txwv ntawm thermoplastic hmoov txheej yog:

polyethylene

Polyethylene hmoov yog thawj thermoplastic hmoov txheej muab rau kev lag luam. Polyethylene muab cov txheej txheem ntawm cov tshuaj tiv thaiv zoo heev thiab toughness nrog cov khoom siv hluav taws xob zoo. Qhov saum npoo ntawm cov txheej txheej no yog du, sov rau qhov kov, thiab nruab nrab gloss. Polyethylene coatings muaj cov khoom tso tawm zoo, tso cai rau cov khoom nplaum nplaum los ntawm lawv qhov chaw. Yog li ntawd, lawv pom ntau yam kev siv hauv txheej txheej ntawm cov khoom siv hauv chav kuaj.

Polypropylene

Raws li cov txheej txheem saum npoo, polypropylene muaj ntau yam khoom muaj txiaj ntsig nws muaj raws li cov khoom siv yas. vim natural polypropylene yog inert heev, nws qhia tau hais tias me ntsis nyiam mus ua raws li hlau los yog lwm yam substrates. Cov yam ntxwv no ua rau nws tsim nyog los hloov kho cov natural polypropylene thaum nws yog siv los ua cov hmoov txheej txheej, kom adhesion ntawm txheej rau substrate tuaj yeem tau.

nylon

Nylon hmoov yuav luag tag nrho raws li hom 11 nylon resin thiab muab cov txheej tawv tawv uas muaj kev puas tsuaj zoo heev, hnav, thiab kev cuam tshuam tsis zoo nrog cov coefficient tsawg ntawm kev sib txhuam thaum thov dhau qhov tsim nyog. primer. Ib qho kev nthuav dav tshaj plaws ntawm kev siv nylon hmoov txheej yog nyob rau hauv kev tsim kho tshuab. Nws qhov sib xyaw ua ke ntawm cov coefficient qis ntawm kev sib txhuam thiab lubricity zoo ua rau nws zoo tagnrho rau kev zawv zawg thiab tig cov kabmob xws li tsheb spline shafts, relay plungers, thiab hloov rab diav rawg, thiab lwm yam kabmob ntawm cov khoom siv, cov khoom siv ua liaj ua teb, thiab textile machinery.

polyvinyl

Polyvinyl chloride hmoov coatings muaj zoo sab nrauv durability thiab muab coatings nrog ib tug nruab nrab-mos glossy tag. Lawv sib raug zoo rau feem ntau cov hlau substrate thaum thov tshaj ib tug haum primer. Cov txheej txheem no yuav tiv taus cov kev ntxhov siab ntawm cov hlau fabrication xws li khoov, embossing, thiab kos duab.

Thermoplastic Polyester

Thermoplastic polyester hmoov txheej muaj qhov zoo adhesion rau feem ntau cov hlau substrates yam tsis tas yuav tsum muaj primer, thiab pom zoo rau sab nrauv weatherability. Lawv yog cov coatings zoo rau cov khoom xws li cov rooj tog hlau sab nraum zoov.
Cov hmoov Thermoplastic yog qhov tsim nyog tshaj plaws rau cov khoom txheej uas yuav tsum tau muaj cov yeeb yaj kiab tuab rau kev ua haujlwm hnyav. Lawv tsis generally sib tw nyob rau hauv tib lub lag luam raws li kua xim.
