Autoplasticine. Ib qho yooj yim kho rau cov teeb meem nyuaj

Qhov muaj pes tsawg leeg ntawm autoplasticine

Txij thaum ntawd los, muaj pes tsawg leeg ntawm plasticine tsis tau hloov pauv ntau, yog li qee tus tswv tsheb txawm tias tam sim no nyob rau hauv cov xwm txheej tseem ceeb tswj nrog cov menyuam yaus cov plasticine, raws li muaj pov thawj los ntawm ntau cov kev tshuaj xyuas. Qhov kawg tab sis tsis kawg, vim hais tias xws li plasticine tuaj yeem ua ntau xim.

Cov khoom ntawm cov khoom muaj xws li:

• Gypsum siv los ua ib qho chaw muab tub lim - 65%.
• Vaseline - 10%.
• Txiv qaub - 5%.
• Kev sib xyaw ntawm lanolin thiab stearic acid - 20%.

Rau kev siv hauv cov khoom siv tshuaj tsis siv neeg, cov khoom tshwj xeeb yog ntxiv rau cov yas yas uas tsis muaj cov txheej txheem corrosion.

Autoplasticine yog tsim los ntawm ob lub hauv paus - dej lossis roj, thiab ob qho tib si siv los tiv thaiv tsheb. Thawj pab pawg yog tus cwj pwm los ntawm kev muaj peev xwm ua kom qhuav hauv huab cua, thaum tswj nws cov qauv qub (cov cuab yeej no yog siv thaum sib khi cov pob qij txha thiab qhov khoob). Cov pab pawg thib ob yog exfoliating autoplastics, lawv yog cov yas thiab tsis qhuav tawm, yog li ntawd lawv tau siv los ua cov tshuaj tiv thaiv hauv zos rau hauv qab thiab lwm yam hauv lub cev ntawm lub tsheb.

autoplasticine yog dab tsi?

Kev siv lub ntsiab ntawm cov khoom:

1. Kev tiv thaiv ntawm bolts los ntawm corrosion.
2. Raws li ib tug anticorrosive neeg sawv cev (ua ke nrog ib tug xeb converter).
3. Sealing ib feem ntawm lub cev.

Autoplasticine yog siv los tiv thaiv cov pob qij txha thiab qhov khoob hauv qab ntawm lub tsheb los ntawm cov khoom me me. Qhov no pab txhawb lawv cov kev tshem tawm tom ntej thaum ntxuav nrog cov tshuaj zawv plaub hau lossis dej dawb, thaum lub ntsiab txheej tsis puas. Tom qab ntawd, kev ua haujlwm ntxiv nrog nws pib-sealants tuaj yeem ua tau.

Txhawm rau tiv thaiv xeb, dej-raws li autoplastics yog siv (lub hom phiaj thiab muaj pes tsawg leeg yog feem ntau qhia ntawm lub ntim ntawm cov khoom). Xws li lub foob tuav zoo ntawm txhua qhov chaw, tsis raug tshav ntuj, tsis muaj tshuaj lom, thiab tsis decompose, txawm nyob rau theem siab ntawm sulfur dioxide, nitrogen lossis carbon dioxide nyob rau hauv qhov chaw.

Nrog rau daim ntawv thov tas mus li, cov khoom siv pab txo lub suab nrov ntawm lub cav khiav: lub suab nqus tau ua kom ntseeg tau los ntawm cov qauv cellular ntawm cov khoom. Txoj kev no tshwj xeeb tshaj yog siv rau cov chaw hauv lub tsheb uas nws tsis tuaj yeem siv cov kua sealant. Cov no suav nrog kev sib tshuam ntawm lub tsheb tis nrog qhov chaw pib, tis flanging ntsiab lus, daim ntawv tso cai, kev sib txuas ceev rau nres hoses thiab cov hlab. Nyob rau hauv rooj plaub tom kawg, lawv ntxiv fixation yog ib txhij ua.

Kev sib koom ua ke ntawm kev siv autoplasticine thiab xeb hloov pauv yog raws li hauv qab no. Qhov saum npoo yog kom qhuav thiab ntxuav. Ua ntej, ib txheej ntawm lub converter yog siv, thiab tom qab ntawd cov teeb meem hauv cheeb tsam (fasteners, log arch liners, sab hauv ntawm bumpers) yog ua tiav nrog autoplasticine. Qee cov neeg siv tshuaj xyuas qhia tau tias tsuas yog autoplasticine tuaj yeem siv tau, tshwj xeeb tshaj yog thaum lub ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws​​ kaw lus

Cov kev cai yooj yim ntawm kev xaiv

Nws yog tsim nyog xaiv autoplasticine tsis ntau npaum li cas rau nws tus nqi, tab sis rau nws tactile rhiab heev: cov khoom muag yog nkig dua, thiab, txawm hais tias nws yog yooj yim dua rau thov, nws tuav tsis zoo nyob rau hauv lub kawg. Hard plasticine yog yooj yim dua los muab cov duab xav tau.

Cov khoom nplaum ntawm cov autoplasticines niaj hnub no tsis nyob ntawm cov khoom uas raug kaw, yog li nws raug nquahu kom xaiv cov khoom raws li qhov sib xws thiab muaj pes tsawg leeg ntawm cov khoom, tsom mus rau qhov kev ua haujlwm yuav tsum tau ua.

Cov kev txwv ntawm cov khoom muaj xws li qhov tseeb hais tias cov dej uas muaj autoplasticine poob nws elasticity nyob rau hauv hnyav frosts, tawg nyob rau hauv cov chaw ntawm nws daim ntawv thov. Kev sim siv cov roj-soluble formulations kuj tsis muaj kev vam meej, txij li thaum tsis kub, autoplasticine tsis thicken thiab delaminate. Los ntawm txoj kev, cov khoom tseem tsis haum ntawm qhov kub siab tshaj 30 ... 35ºС, txij li thaum nws pib yaj.
