Qhov tshwm sim ntawm dripping, sagging thiab tsis sib xws xim zaj duab xis nyob rau saum npoo ntawm lub hauv paus txheej tuaj yeem hu ua xim saging.
Cov laj thawj tseem ceeb:
1. Cov xim uas npaj tau yog nyias dhau, qhov adhesion tsis zoo, thiab qee cov xim ntws los ntawm qhov kev txiav txim ntawm lub ntiajteb txawj nqus;
2. Cov xim pleev xim los yog xim pleev xim yog tuab heev, thiab cov xim pleev xim yog hnyav dhau los poob;Qhov kub ntawm qhov kev tsim kho ib puag ncig tsawg dhau, thiab cov xim pleev xim dries maj mam;
3. Cov xim muaj ntau cov xim hnyav, thiab qee cov xim sags;
4. Qhov saum npoo ntawm lub hauv paus txheej ntawm cov khoom yog tsis sib xws, lub thickness ntawm cov xim zaj duab xis yog tsis sib xws, lub ziab ceev yog txawv, thiab ib feem ntawm cov xim ntawm cov xim uas yog tuab heev yog ib qho yooj yim mus poob;
5. Muaj roj, dej thiab lwm yam av nyob rau saum npoo ntawm lub hauv paus txheej ntawm cov khoom uas tsis sib haum nrog cov xim, uas cuam tshuam rau kev sib txuas thiab ua rau cov xim pleev xim rau sag.
1. Nws yog ib qho tsim nyog los xaiv cov xim zoo nkauj thiab diluent nrog tus nqi tsim nyog volatilization, thiab tswj nws cov nyiaj infiltration.
2. Qhov saum npoo ntawm cov khoom yuav tsum tau kho kom tiaj tus thiab du, thiab tshem tawm cov av xws li cov roj thiab dej.
3. Qhov kub ntawm qhov chaw tsim kho yuav tsum ua kom tau raws li cov qauv kev cai ntawm hom xim, xws li cov kua roj vanish yuav tsum yog 20 txog 27 degrees Celsius, thiab cov xim yuav tsum tau ua tiav hauv 3 teev.
4. Thaum pleev xim rau, nws yuav tsum tau ua raws li cov txheej txheem txheej txheem: thawj ntsug, kab rov tav, oblique, thiab thaum kawg vertically du cov xim ua rau cov txheej txheej zaj duab xis thickness ntawm cov xim sib xws thiab zoo ib yam.
5. Kev txav ceev ntawm rab phom txau thiab qhov kev ncua deb ntawm cov khoom yuav tsum tau tswj tsis tu ncua, raws li cov txheej txheem txheej txheem, thawj zaug tshuaj tsuag vertically, lub nplhaib txau, thiab tom qab ntawd tshuaj tsuag tom qab kom cov xim zaj duab xis sib xws, tuab thiab sib xws.
Qhov nto roughness ntawm cov xim zaj duab xis yog tshwj xeeb tshaj yog manifested: tom qab cov xim yog filmed, nto yog tsis sib xws, thiab muaj cov xuab zeb zoo li pob los yog npuas me me.
Cov laj thawj tseem ceeb yog:
1. Muaj ntau cov xim lossis cov khoom hauv cov xim yog ntxhib dhau;Cov xim nws tus kheej tsis huv, tov nrog cov khib nyiab, thiab siv tsis muaj sieve;
2. Lub ambient kub thaum sib tov xim yog tsawg, thiab cov npuas nyob rau hauv cov xim yuav tsis dispersed thiab tawm;
3. Qhov saum npoo ntawm cov khoom tsis raug ntxuav, muaj cov xuab zeb thiab lwm cov khib nyiab, uas tau muab sib xyaw rau hauv cov xim pleev xim zaj duab xis thaum pleev xim;
4. Cov thawv ntim khoom siv (cov txhuam hniav, cov thoob pleev xim, cov phom tshuaj, thiab lwm yam) tsis huv, thiab muaj cov khib nyiab seem coj los rau hauv cov xim;
5. Kev tu thiab kev tiv thaiv ib puag ncig ntawm kev tsim kho tsis txaus, thiab muaj plua plav, cua thiab xuab zeb thiab lwm yam khib nyiab daig rau ntawm txhuam los yog poob ntawm cov xim pleev xim.
Txhawm rau tiv thaiv qhov ntxhib ntawm cov xim zaj duab xis, peb kuj muaj ntau yam kev ceev faj:
1. Txhawm rau xaiv cov xim zoo nkauj, nws yuav tsum tau ua tib zoo tshuaj xyuas ua ntej siv, sib npaug sib npaug, thiab tom qab ntawd siv tom qab tsis muaj npuas.
2. Ua tib zoo saib xyuas qhov chaw ntawm qhov khoom thiab ua kom nws tiaj tus, du thiab qhuav.
3. Nws yog ib qho tseem ceeb heev uas yuav tsum tau npaj kom tsim nyog raws li kev tsim kho ntawm txhua hom kev ua haujlwm kom ntseeg tau tias qhov chaw pleev xim rau kev tsim kho tsis muaj cov khib nyiab thiab plua plav.
4. Nws yuav tsum tau muab sau tseg tias nws tsis pub rov qab siv cov khoom siv uas muaj cov qauv sib txawv thiab cov xim sib txawv, thiab cov khoom seem yuav tsum tau muab tshem tawm ua ntej siv.
