Tsis ntev los no, Steven tau txais cov lus tawm tswv yim los ntawm qee tus neeg siv khoom: koj lub zog nplaum tsis zoo, nws tsis ruaj khov, nws yuav curly tom qab ib hmos. Puas yog qhov zoo ntawm cov nplaum tsis zoo?

Thaum xub thawj, Steven xav tias lub Hoobkas tsim khoom tsis nruj heev, qhov sib piv tsis txaus. Muaj ib lub sijhawm, lub Hoobkas raug kaw rau kev tshuaj xyuas. Xav txog vim li cas qhov no thiaj li tshwm sim.

Vim tias qhov teeb meem no tshwm sim sai heev tsis ntev los no, thiab tsuas muaj ob peb lub tsev luam ntawv xwb, cov neeg siv khoom yuav tsum tsim cov fwj ntim khoom. Thiab qhov ntawd ua rau kuv xav.

 

Ua ntej, cia peb tshuaj xyuas qhov ua rau muaj teeb meem: nplaum

Cov khoom sib xyaw ntawm cov nplaum feem ntau muab faib ua ob hom: A dej nplaum B kub yaj nplaum.

Cov kua nplaum dej, tsis tas yuav hais, nws yog ib hom kua nplaum uas muaj dej ua cov kuab tshuaj lossis cov kua nplaum sib xyaw ua ke, qhov nplaum pib tsis zoo, yog qhov koj hu ua daim nplaum thaum xub thawj tsis muaj zog heev, qhov no yog vim cov khoom ntawm cov kua nplaum, cov kua nplaum tsis muaj zog heev thaum xub thawj, tab sis nrog kev txhim kho ntawm lub sijhawm, daim ntawv lo yuav muaj zog dua, ntev dua, qhov ntau dua viscous.

Cov nplaum kub yaj, cov neeg luam ntawv qub yuav tsum paub zoo dua kuv, yog ib hom yas nplaum, rau qee qhov kub thiab txias nrog qhov kub hloov pauv thiab hloov nws lub cev, siv cov ntawv nplaum no, muaj zog pib nplaum, txuas yog qhov pib muaj zog heev, tab sis nrog qhov nce ntawm qhov kub thiab sijhawm, viscosity maj mam ua qaug zog, cov kua nplaum no cuam tshuam los ntawm qhov kub thiab sijhawm.

Yog li ntawd, puas yog vim kuv siv daim ntawv nplaum uas muaj dej, ua rau daim ntawv lo tsis nplaum txaus?

Qhov tseeb, nws tsis paub meej, cia peb saib, qhov xwm txheej dav dav ntawm daim ntawv lo viscosity tsis txaus, rooj plaub ntawm tus qauv yog dab tsi?

1. Cov fwj yas.

Feem ntau xaiv cov neeg siv khoom siv tes ua daim ntawv lo, yog cov chaw tsim khoom, txhaj tshuaj yas, nqes mus rau hauv kab ntau lawm, nws tab tom yuav pib sau ntawv.

Cia peb los saib ib yam tshuaj uas tseem ceeb hauv kev tsim cov fwj yas txhaj tshuaj: Tus neeg sawv cev tso tawm.

Tus neeg sawv cev tso tawm yog dab tsi?

Nws yog ib yam khoom ua haujlwm ntawm cov pwm thiab cov khoom tiav. Cov neeg sawv cev tso tawm yog cov tshuaj tiv taus thiab tsis yaj thaum sib cuag nrog cov khoom siv tshuaj ntawm cov resins sib txawv, tshwj xeeb tshaj yog styrene thiab amines. Cov neeg sawv cev tso tawm kuj muaj cov khoom tiv taus cua sov thiab kev ntxhov siab, tsis yooj yim rau decompose lossis hnav;

Cov Khoom: Nws yog ib txheej txheej interfacial uas siv rau ob qhov chaw uas yooj yim lo rau ib leeg. Nws ua rau cov chaw yooj yim cais tawm, du thiab huv si.

2, lub varnish

Tseem hu ua qhov twg dej, resin yog cov khoom siv zaj duab xis tseem ceeb ntxiv rau cov kuab tshuaj ntawm cov xim. Vim tias txheej thiab besmear yog pob tshab, kuj hu ua txheej pob tshab raws li. Txheej rau ntawm qhov chaw ntawm cov khoom, qhuav kom tsim cov zaj duab xis du, qhia qhov chaw ntawm cov qauv qub.

Cov Khoom: Ib txheej tiv thaiv du rau ntawm qhov chaw ntawm ib yam khoom.

3. Lwm tus

Cov khoom tiav lawm uas nyuam qhuav luam tawm yuav raug txau nrog hmoov talcum thiab lwm yam khoom, xws li lub txee Hoobkas kuj tseem yuav raug txau nrog cov tshuaj tiv thaiv roj.

Cov xwm txheej no yuav zoo li cov nplaum nplaum tsis muaj zog.

Cov tshuaj lom neeg ntawm cov kua nplaum feem ntau muaj cov vinyl acetate, varnish lossis cov neeg sawv cev tso tawm feem ntau muaj xylene thiab silicone roj. Ib qho ntawm cov khoom no yuav rhuav tshem cov kua nplaum, thiab lwm qhov yuav tsis cuam tshuam nrog nws. Tsis tas li ntawd, yuav tsum tau muab lo rau ntawm qhov chaw ntawm cov khoom muaj lwm cov hmoov av lossis cov kua tiv thaiv, yog li cov nplaum thiab cov khoom tsis tuaj yeem nplaum tag nrho.

Kuj tseem muaj qhov teeb meem uas peb txhawj xeeb txhua lub sijhawm: daim nplaum tsis nplaum

Yog li ntawd, peb yuav ua li cas nrog qhov xwm txheej no?

Nws yooj yim: ntxuav qhov chaw.
