Polyester cob: zog thiab daim ntawv thov, nta ntawm

Lub polyester cob muaj ib tug heev dav uas duav txhua yam ntawm daim ntawv thov. Cov khoom uas yog tau los ntawm tshuaj ntau lawm los ntawm ib tug tej yam complex txheej txheem ntawm combining thiab ua ntawm cov tshuaj. Lub polyester cob muaj pes tsawg leeg yog cov alcohols, lawv yog tsim nyob rau raws li ib tug tshwm sim ntawm refining mepropriyaty. Yog xav paub ntxiv txog polyester resins no.

Qhov no glycols (e.g., monoethylene glycol, diethylene, triethylene, propylene, butylene), raws li zoo raws li glycerol, pentaerythritol, xylitol. Acids: orthophthalic acid, adipic acid, sebacic acid, terephthalic acid, maleic anhydride, xws li methacrylic thiab acrylic acid. Yog hais tias tsim nyog, cov hloov ntawm polyester resins muaj daim ntaub ntawv ntawm cov zaub roj thiab rog, raws li zoo raws li cob acids.

Nrog rau kev siv ntawm cov khoom tsim ib tug ntau yam ntawm cov khoom. Qhov no hull rau tej nkoj nquam, raws li zoo raws li ntau ntawm cov ntsiab lus rau lawv, nws yog chav dej, surfboards, etc.

Nws siv ntawm cov tebchaw tau nyob rau hauv ntau yam teb ntawm manufacturing, nyob rau hauv qhuav ntawm khoom resistant rau tshuaj. Lawv kom meej meej qhia lawv tus kheej nyob rau hauv zus tau tej cov neeg mus ncig tebchaws thiab kev ua si cov khoom, raws li zoo raws li lub creation ntawm cov kav dej accessories, piv txwv li, muaj coob tus neeg tau hnov lub tswvyim ntawm acrylic lub dab da dej los yog da dej acrylic tais, thiab lwm yam

Polyester resins muaj zoo yav tom ntej yam ntxwv. Rau cov neeg muaj xws li:

• kuj txog cov kev hloov nyob rau hauv kub (kub mas nws txawv nyob rau hauv ntau 60 - 100 degrees);
• cim siab txhua yam kuj (tom qab tag nrho solidification muaj zog thiab hardness theem);
• kuj mus tshuaj ntawm tshuaj muaj pes tsawg leeg (tshwj tsis yog rau industrial);
• hnav tsis kam thiab ntev kev pab cuam lub neej ntawm cov khoom los ntawm polyester cob, thiab cov thawj zoo cov yam ntxwv yog kiag li tsis txo;
• khoom ntawm lub tib cov ntaub ntawv zoo tshem tawm shrinkage.

Ua hauj lwm nrog ib tug khoom xws li polyester cob, nws tsis ua rau complexity thiab yuav tsum tau me ntsis professionalism thiab kev. Qhov loj tshaj plaws - mus soj ntsuam cov yooj yim kev nyab xeeb kev cai rau siv qhov no muaj pes tsawg leeg thiab coj mus rau hauv tus account tej nuances. Piv txwv li, rau cov cob thaum lub sij hawm khov txheej txheem thiab qhov kawg khoom muaj saum toj no-piav thaj chaw ntawm lub zog thiab kev cia siab, nws yog tsim nyog los siv tshwj xeeb hardeners.

Tsis tas li ntawd nco ntsoov tias tom qab nws cob thiab hardener yuav tsum ua hauj lwm sai sai rau cov txheej txheem pib lub exothermic cov tshuaj tiv thaiv. Tom qab ua ntawv thov cov ntaub ntawv uas tsim nyog muab rau nws ntau li ntau lub sij hawm solidify thiab coj tus yam zoo.

Yog hais tias koj xav nyob rau hauv yuav cov khoom no, koj yuav tsum coj tiag cov kev xaiv ntawm chaw muag khoom. Nws yuav tsum muab tag nrho cov tsim nyog daim ntawv pov rau lawv cov khoom. Ces koj yuav tau phem ntawm nws cov high quality. Tom qab tag nrho, tsis zoo no tseem ceeb heev rau peb. A rau cov khoom xws li polyester cob yog nce yuav tsum tau. Uas yog vim li cas koj yuav tsum tiag nug lawv purchase.
