Lub sijhawm dhau mus, cov roj hmab, txawm tias tau ua raws li cov cai tswjfwm, tuaj yeem ua npub. Tab sis hmoov zoo, nws tuaj yeem rov qab los rau nws cov khoom qub elasticity hauv tsev (nyob rau tib lub sijhawm, qib hnav tsis kam tuaj yeem txo). Nws tsis tas yuav muaj cov tshuaj tshwj xeeb. Txhua yam khoom koj xav tau tuaj yeem nyob hauv tsev.

Qhov tseem ceeb ntawm txoj kev yog kom ntub cov khoom siv roj hmab hauv da dej tshwj xeeb. Tom qab lub sijhawm dhau mus, cov khoom saum npoo ntawm cov khoom yuav tsum tau muab ntxuav kom huv thiab qhuav, thaum qhov no tuaj yeem ua tiav hauv daim ntawv sib tw (piv txwv li, yog tias cov ntaub pua plag ntev tau ua tiav).
Lub sijhawm ntawm kev ntub dej yog nyob ntawm ntau qhov tsis sib xws, tshwj xeeb ntawm qhov ntev ntawm cov khoom siv roj hmab thiab qib hardening ntawm cov khoom (qhov no yuav tsum tau txiav txim siab ua ntej muag cov roj hmab). Tab sis li caskev xyaum qhia tau hais tias koj yuav tsum tau tsau rau hauv da dej tsawg kawg 2-3 teev, vim roj av tsis ua haujlwm tam sim.
Ammonia
Cov peev txheej ntawm ammonia yog qhov dav. Softening roj hmab yog ib txoj hauv kev siv cov tshuaj no. Ntau tus kws tshaj lij piav qhia meej txog yuav ua li cas muag roj hmab hauv txoj kev no. Koj tuaj yeem ua kom cov khoom muag muag los ntawm kev ua raws li txoj kev npaj no:
- Xaiv lub thawv ntawm qhov loj.
- Ua ntej koj soften cov roj hmab, koj yuav tsum dilute ammonia nyob rau hauv tus nqi ntawm cov dej (feem 1: 7).
- Soak cov khoom hauv qhov kev daws teeb meem no ntev tshaj li ib teev (tsis muaj teeb meem koj yuav tsum khaws cov roj hmab hauv ammonia ntev dua li lub sijhawm teev tseg, yog tias tom qab 30 feeb nws pom tias cov khoom tsis ua kom elastic dua., ces koj yuav tsum sim lwm txoj kev).
- Tom qab qhov xav tau ntawm qhov muag tau rov qab los, tshem cov roj hmab los ntawm da dej thiab yaug nrog dej huv.
Cov khoom siv qhuav refurbished tsuas yog nyob rau hauv chav tsev kub. Hnub ci ncaj qha thiab qhov kub thiab txias tuaj yeem cuam tshuam qhov xwm txheej ntawm cov khoom.
Kev haus cawv muaj cov khoom zoo sib xws, tab sis glycerin tseem yuav tsum tau ua. Yog hais tias cov roj hmab yog hardened, logic yuav qhia koj yuav ua li cas soften nws. Cov khoom puas yuav tsum tau tsau rau hauv kev kho mob cawv rau ob peb teev, tom qab ntawd nws yuav tsum tau muab tshem tawm, ntxuav nrog dej sov nrog xab npum. Tom qab qhov saum npoo tau qhuav lawm, koj yuav tsum rub lub glycerin siv daim ntaub los yog daim txhuam cev. Glycerinyuav tsum muaj me ntsis, qhov tshaj yuav tsum tau muab tshem tawm. Hloov chaw, koj tuaj yeem nqa cov roj tsheb (qhov no, koj tuaj yeem siv cov khoom tom qab 30 feeb xwb).
Silicone thiab castor roj
Cov tshuaj hauv tsev no rau kev rov ua kom elasticity muaj qee qhov tsis zoo. Ib qho ntawm lawv yog cov nyhuv luv luv, uas tsis yog ib txwm yooj yim. Tab sis tseem muaj qee qhov txiaj ntsig:
- muaj (silicone tuaj yeem yuav ntawm txhua lub khw tshwj xeeb, thiab nws tus nqi qis);
- tsis tas yuav raug ncua ntev (cov khoom lag luam tau npaj siv tsis pub dhau 30 feeb tom qab pib txheej txheem);
- tsis tas yuav nrhiav cov thawv loj rau cov khoom ntub dej (ua ntej muag cov roj hmab nrog silicone, qhov no tsis tsim nyog).
Cov yam ntxwv no kuj siv tau rau cov roj castor. Cov tshuaj muaj peev xwm nkag mus rau hauv cov qauv ntawm cov roj hmab, uas hloov nws cov khoom. Tab sis nws kuj yaug tawm yooj yim.
