Yog li ntawd, puas yog epoxy resin tib yam li acrylic?
Acrylic cob (tab sis tsis acrylic xim emulsion, uas yog lub hauv paus ntawm acrylic xim) yog cov thermoplastic, uas txhais tau hais tias nws yog ib pawg ntawm cov yas uas tuaj yeem ua kom sov thiab ua haujlwm ntau zaus, thaum polyester cob thiab epoxy yog cov thermosetting plastics, uas siv cov cua sov los yog cov catalyst kom solidify rau hauv cov khoom loj uas yeej
Tom qab, lo lus nug yog, yog resin ib acrylic? Ib Acrylic cob yog thermoplastic los yog thermosetting yas khoom tau los ntawm acrylic acid, methacrylic acid los yog lwm yam sib txuas. Ib qho piv txwv yog polyhydroxyethylmethacrylate, uas ua rau crosslinked polymer thaum kho nrog polyisocyanates. Cov ntaub ntawv zoo li no yog ib qho tseem ceeb hauv qee cov xim.
Tib neeg kuj nug, resin puas zoo dua acrylic?
Nyob rau hauv cov ntaub ntawv ntawm cob tus cob tiag tiag undergoes cov tshuaj tiv thaiv nyob rau hauv cov pwm thiab kho los ntawm ib tug kua rau hauv ib tug khoom. Nyob rau hauv cov ntaub ntawv ntawm acrylic lub hlau cov khoom yog melted thiab poured rau hauv pwm kom txias. Thawj qhov pom tseeb sib txawv yog tus nqi. Resin li ntawm 2-4x li kim li acrylic xim.
Puas yog acrylic resin tshuaj lom?
Feem ntau ntawm cov hniav cuav yog tsim los ntawm kev kho cua sov acrylic cob uas ntseeg tias yuav ua rau muaj kev tso tawm ntawm qee yam tshuaj lom tshuaj xws li formaldehyde, methyl methacrylate, methacrylate acid thiab benzoic acid, ua rau muaj kev cuam tshuam loj hauv cov ntaub so ntswg ib puag ncig.

Puas yog txhua chav dej qhov siab tib yam?
Qhov siab ntawm chav dej yog ntsuas los ntawm hauv pem teb mus rau saum lub rooj zaum. Qhov siab sib txawv txaus kom pom tau. Feem ntau, lawv poob qhov chaw ntawm 15 "thiab 19", nrog rau cov chav dej hauv qab 17 ". Txawm li cas los xij, lub rooj zaum qhov siab hauv chav dej, dab tsi Kohler hais txog Comfort Height® chav dej, ntsuas 17 "los yog ntau dua
Dab tsi yog tib neeg engineering thiab tib neeg yam xwm txheej thiab ergonomics cuam tshuam li cas?
Ergonomics (lossis tib neeg yam tseem ceeb) yog kev qhuab qhia kev tshawb fawb txog kev nkag siab ntawm kev sib cuam tshuam ntawm tib neeg thiab lwm yam hauv lub cev, thiab kev ua haujlwm uas siv txoj kev xav, cov hauv paus ntsiab lus, cov ntaub ntawv thiab cov txheej txheem los tsim kom zoo rau tib neeg kev noj qab haus huv thiab kev ua haujlwm tag nrho
Puas yog magazine thiab clip yog tib yam?
Cov mos txwv clip yog ib qho cuab yeej siv los khaws cov khoom sib tw ntawm cov mos txwv ua ke ua ib chav tsev uas npaj txhij rau kev ntxig rau hauv cov ntawv xov xwm ntawm rab phom. Aclip yog ib qho cuab yeej yooj yim heev uas feem ntau yog ua los ntawm steelstamping
Puas yog vinyl thiab yas yog tib yam?
Raws li adjectives qhov txawv ntawm vinyl thiab yas yog vinyl yog (chemistry) uas muaj cov vinyl radical thaum yas muaj peev xwm ua molded; malleable, yoog raws, pliant
Vim li cas nws tseem ceeb los txiav cov plasmid thiab tib neeg DNA nrog tib yam kev txwv enzyme?
Cov enzymes no tseem ceeb vim tias lawv tso cai rau cov noob tshwj xeeb txiav tawm ntawm qhov chaw chromosome. Lawv kuj txiav cov kab mob plasmids. Siv tib yam kev txwv endonuclease enzyme los txiav qhib lub plasmid raws li yog siv los txiav cov noob los ntawm cov chromosome tau ua tiav cov nplaum nplaum uas tsim tawm
