Cov khoom yas txav yooj yim yooj yim thiab feem ntau, thaum ntau yam xws li yog kev nyiam pov pov tseg. Yuav kom daws tau qhov teeb meem no, koj yuav tsum yuav cov khoom lag luam zoo thiab zoo uas yuav tso cai rau koj kom nrawm thiab muaj kev cuam tshuam rau cov kua yas.
Cov lus sib xyaw rau cov ntawv cog lus plastics: cov yam ntxwv tseem ceeb
Ib qho chaw ua haujlwm yas ua ke yog feem ntau muaj kev sib xyaw nrog cov kuab tshuaj tshwj xeeb uas tsim rau polystyrene. Qhov sib xyaw ua ke ntuag cov khaubncaws sab nraud povtseg sab sauv ntawm cov khoom siv. Yog tias cov ntu smeared nrog cov cuab yeej no tau muab sib xyaw ua ke, lawv sib koom ua ke, ua ib qho. Tom qab cov yas qhuav tas, nws yuav tsis muaj peev xwm cais ob qhov sib txuas nrawm.
Ntxiv rau, pob tshab polystyrene tseem tseem ntxiv rau xws li kua nplaum, uas ua rau cov kua ua kom pom tseeb thiab siv tau yooj yim. Txawm li cas los xij, tseem muaj cov ua kua zoo ua rau ntawm kev ua lag luam, piv txwv li, Revell, ua kua nplaum rau gluing qhov chaw pob tshab.
Cov tshuaj sib tov uas zoo tshaj plaws rau kev ua cov plastics
Rau kev ua haujlwm nrog cov yas niaj hnub no, muaj ob qho tib si thoob ntiaj teb thiab cov cuab yeej tshwj xeeb uas tso cai rau koj kom khov kho thiab ntseeg tau txuas cov yas ntsej muag. Qhov tom kawg yog cov khoom siv nyuaj. Qhov tseeb, qhov no yog kev tsim khoom tsim ntawm lub hauv paus ntawm polymers. Plastics daim ntawv cog lus tsawg dua qee yam ntawm lwm cov ntaub ntawv (piv txwv li, ntoo lossis tawv) vim nws qhov adhesion tsis tshua muaj. Thiab yog li ntawd, txhawm rau ua haujlwm nrog nws, koj yuav tsum xaiv cov khoom sib koom ua ke zoo tiag tiag.
Muaj ntau ntawm cov cuab yeej zoo li no ntawm cov txee ntawm cov khw muag khoom kho vajtse, tab sis ua qhov xaiv qhov yog tsis yooj yim. Qhov nrov tshaj plaws thiab zoo tshaj plaws yog cov hauv qab no:
- Lub zog Plast;
- kua nplaum "Moment";
- muaj pes tsawg leeg Muaj Muaj Zog Plast;
- AKFIX kua nplaum;
- UHU kua nplaum.
Yog tias koj xav tau txoj kev sib txuas zoo heev, cov kws tshaj lij pom zoo siv cov qauv tshwj xeeb uas tau tsim tshwj xeeb rau cov plastics.
Kev xaiv cov nplaum raws li hom yas
Muaj ntau ntau yam ntawm cov yas nyob hauv lub ntiaj teb, thiab cov kws tshawb nrhiav niaj hnub tseem niaj hnub tsim cov hom tshiab ntawm cov khoom siv li niaj hnub no. Yog li, thiaj li yuav ua kom tau txais txoj kev sib txuas zoo, koj yuav tsum xaiv cov khoom lag luam rau cov hom yas tshwj xeeb.
Kev kho cov thermosetting plastics tsis yooj yim, vim tias cov khoom zoo li no tsis tuaj yeem muag thiab yaj. Coob leej ntau tus neeg paub txog hom plastics; nws feem ntau yog siv los ua cov nyees khawm rau khaub ncaws, tsev nyob rau cov koob yees duab, cov thom khwm, ntsaws thiab cov ntim tshuaj tsw qab. Txhawm rau kho cov khoom lag luam, koj yuav tsum siv cov cuab yeej tshwj xeeb uas tsim los ntawm BF-2 lossis BF-4 hom.
Koj yuav tsum ua haujlwm nrog lawv zoo li no: ua ntej, koj yuav tsum tau degrease pob txha tawg, tom qab ntawd thov siv kua nplaum rau qhov chaw qhuav thiab ua kom cov plaub hau ua kom tiav me ntsis. Tom qab ntawd, txheej thib ob yog thov. Nws tau qhuav rau ob feeb, thiab tom qab ntawd cov nplais yog nruj nreem tawm tsam ib lwm thiab muab tso rau hauv qab xovxwm. Lub tswv yim zoo yuav ua tiav tom qab 3 hnub.
Cov thermoplastics kuj tseem yuav xav tau cov khoom lag luam cais. Xws li cov khoom muag muag nyob rau hauv qhov kev nqis tes ntawm qhov kub thiab txias, thiab vim li ntawd nws feem ntau tau nrawm nrog kev pab ntawm cov kuab tshuaj. Feem ntau, cwjmem, xab npum ntxuav tais, combs, tsom iav qhov muag, menyuam cov khoom ua si yog tsim los ntawm nws.
Koj tuaj yeem ua ib qho txhais tau rau fastening khoom los ntawm cov ntaub ntawv zoo li ntawm koj tus kheej. Txhawm rau ua qhov no, koj yuav tsum sib tov 1 feem ntawm celluloid sawdust thiab 2 feem ntawm cov kuab tshuaj. Khaws qhov sib tov no tso rau hauv qab hau. Tsis tas li ntawd, rau kev ua haujlwm nrog cov khoom siv thermoplastic, txhais tau tias "MC-1", "Mars", "Ts-1", uas cov kws tshaj lij xav txog qhov muaj pes tsawg leeg zoo tshaj plaws, zoo meej.
Nws tsis yooj yim heev los xaiv cov nplaum zoo tshaj plaws thiab zoo rau cov yas, vim tias qhov no yuav tsum muaj kev paub tshwj xeeb, nrog rau kev ua haujlwm nrog cov khoom siv zoo li no.
