Silicone pwm tau siv nyob rau hauv lub neej txhua hnub ntev. Kev ua tau zoo thiab kev yooj yim ntawm lawv siv tau rov ua pov thawj lawv tus kheej. Thiab yog tias ua ntej nws yooj yim dua los yuav lawv hauv khw tshwj xeeb, tam sim no koj tuaj yeem ua silicone rau pwm nrog koj tus kheej tes hauv tsev. Qhov kev ua haujlwm yooj yim thiab siv zog ua haujlwm no muaj rau cov neeg uas tsis muaj tswv yim txog kev tsim kho lossis kho.
Dab tsi yog silicone
Cov khoom no muaj npe nrov rau nws cov yam ntxwv zoo heev: elastic thiab pliable, tab sis tib lub sijhawm ruaj khov thiab txhim khu kev qha. Nws yog ua tsaug rau qhov no uas siv cov silicones tau dhau los ua ntau zaus hauv kev kho, kev tsim kho thiab lwm qhov chaw ntawm lub neej.
Ua ntej tshaj plaws, nws tsim nyog txiav txim siab seb qhov twg tuaj yeem ua los ntawm nws. Rau kev tsim cov pwm, nchuav silicone yog siv. Nyob ntawm seb hom qauv, muaj ntau txoj hauv kev los ua rau lawv. Rau cov ntawv txiav, ib qho txheej txheem yog siv, thiab hauv kev tsim cov txheej txheem ntau dua, piv txwv li, cais lossisvoluminous, silicone khoom yog poured rau hauv ib tug tshwj xeeb npaj matrix.
Cov ntaub ntawv ua los ntawm txoj kev no yog qhov txawv los ntawm kev siv thoob ntiaj teb. Lawv tsim nyog rau nchuav ob qho tib si gypsum los yog melted ciab rau hauv lawv, nrog rau cov khoom hnyav dua xws li resins, molten yas thiab lwm yam ntaub ntawv. Txawm hais tias lawv cov kev ua tau zoo, silicone pwm tuaj yeem tiv taus pob zeb. Qhov yooj yim ntawm lawv siv kuj tau piav qhia los ntawm lawv qhov rov siv tau.
ua tus kheej
Qhov yooj yim tshaj plaws yog ua kom cov pwm sib cais. Nws yog tsim los ntawm pouring cov khoom rau hauv ib tug matrix haum rau cov hom phiaj. Muaj ntau ntau yam ntawm silicone, nyob ntawm seb nws siv li cas. Cov muaj pes tsawg leeg, kev npaj hauv tsev uas yuav tau tham hnub no, yog nchuav ncaj qha rau hauv lub nkoj npaj. Tab sis kuj tseem muaj ntau hom uas siv nrog txhuam tshwj xeeb lossis spatula.
Yog li, txhua yam ntawm silicone tau muab faib ua filling thiab txheej. Ntxiv mus, qhov muaj pes tsawg leeg, muaj ob yam khoom, muaj ntau lub hom phiaj. Nws tuaj yeem siv ob qho tib si rau casting pwm thiab ua cov cam khwb cia, qhov ncauj qhov ntswg thiab lwm yam khoom. Ciab, xab npum, gypsum, resins thiab txawm hlau, xws li tin lossis alloys, tuaj yeem nchuav rau hauv cov qauv ua los ntawm silicone. Nws tuaj yeem siv los tsim cov pob zeb dag thiab lwm yam khoom vaj tsev.
Ua haujlwm nrog silicone
Ua ntej ntawm tag nrho, nws yog qhov yuav tsum tau degrease cov khoom los ntawm qhovdaim ntawv. Peb ua qhov kev kho ntawm cov kab nrib pleb, dents, chips ntawm nws tus kheej, txij li qhov nto ua lub luag haujlwm tseem ceeb heev. Yog tias muaj qhov tsis zoo, lawv yuav tsum tau xuab zeb nrog putty lossis lwm yam khoom siv hauv tsev los tiv thaiv corrosion. Ua ntej pouring silicone, nws yog advisable mus sim nws muaj pes tsawg leeg thiaj li tsis mus lwj cov duab. Rau cais pouring, ib tug ob-ntim muaj pes tsawg leeg yog haum. Ua ntej koj yuav tsum tau ua ib lub thawv uas silicone yuav raug nchuav ncaj qha. Rau kev tsim cov matrix, txhua yam khoom ruaj khov, ruaj khov yuav mus. Nws tuaj yeem yog iav, yas, plywood boards. Koj tseem tuaj yeem siv cov thawv npaj los yog cov thawv ntim khoom. Yog hais tias lub matrix yuav tsum tau ua los ntawm nws tus kheej, ces nws cov khoom yuav tsum tau fastened nrog cov kua nplaum los yog kaw cov khoom.
Nyob rau hauv qab ntawm lub thawv koj yuav tsum tau muab cov txheej txheem plasticine. Qhov siab ntawm nws txheej yuav tsum ncav cuag nruab nrab ntawm qhov siab ntawm lub thawv. Los ntawm saum toj no, plasticine yuav tsum tsis txhob muaj kab nrib pleb, protrusions los yog lwm yam flaws. Qhov smoother ntawm qhov chaw, qhov zoo dua. Ib yam khoom yog muab tso rau sab saum toj ntawm plasticine, los ntawm kev npaj kom tshem tawm cov pwm. Nws yuav tsum tau pre-degreased kom zoo adhesion rau cov khoom. Tom qab ntawd, peb tus kheej ua qhov me me hauv txheej plasticine kom tsis txhob deformation.
Volume xam
Kev tsim cov silicone pib nrog kev suav cov khoom tsim nyog rau kev nchuav. Nws yuav yooj yim dua rau kev suav yog tias koj thawj zaug ncuav xuab zeb lossis lwm yam khoom zoo sib xws rau hauv lub thawv. Qhov ntim ntawm cov khib nyiab ntau yuav yog kwv yees sib npaug ntawm qhov ntim xav tau rau pouring qhov muaj pes tsawg leeg. Sib tov silicone rau pwm los ntawm koj tus kheejxuas tes ua hauv tsev, yuav tsum nyob hauv ib lub nkoj nyias.
Y Kev sib xyaw ntawm silicone
Rau kev tsim cov tshuaj uas yuav tsum tau nchuav rau hauv cov matrix, koj yuav tsum siv ob yam khoom - silicone thiab catalyst. Ib puas feem ntawm cov khoom siv hauv paus yuav xav tau ob lossis peb thiab ib nrab ntawm cov catalyst. Cov tom kawg yog qhov yooj yim tshaj plaws txhaj rau hauv qhov sib tov nrog ib lub syringe. Cov muaj pes tsawg leeg yuav tsum sib xyaw kom zoo.
Nws hardening nyob ntawm qhov kub thiab txias. Yog tias nws siab tshaj plaub caug degrees, qhov no tuaj yeem ua kom nrawm nrawm ntawm qhov sib tov.
Nws yuav tsum nco ntsoov tias txawm tias qhov kub thiab txias nws pib tawv sai sai. Feem ntau cov txheej txheem ntawm solidification ntawm cov kua silicone yog li ob hnub. Nrog rau cov cua sov muaj zog, qhov sib tov pib tawv hauv kaum tsib mus rau nees nkaum feeb. Tsis tas li ntawd, tus nqi ntawm solidification yog cuam tshuam los ntawm tus nqi ntxiv catalyst thiab cov av noo nyob rau hauv chav tsev. Nws raug pom zoo kom siv cov pwm silicone rau lawv lub hom phiaj tsis pub dhau hnub thib peb.
txheej txheem sau
Tsis txhob siv cov roj ntsha silicone thaum ua qauv. Rau cov hom phiaj no, cov khoom siv roj los yog siv quav ciab tau muab. Koj tuaj yeem siv cov tshuaj xab npum es tsis txhob siv cov roj nplaum tshwj xeeb.
Nws yooj yim los ua silicone pwm nrog koj tus kheej tes. Tab sis koj yuav tsum tau ceev faj heev nrog cov txheej txheem pouring. Nws yog qhov zoo tshaj plaws los qhia silicone rau hauv lub matrix raws nws ntug, nyob rau hauv ib tug nyias nyias. Kev nchuav tsis raug yuav ua rau muaj npuas hauv pwm.
Plasticine los ntawm matrix tuaj yeem ua tautshem tawm tam sim tom qab txheej saum toj kawg nkaus tau hardened. Tab sis tseem, nws yuav tsum tau muab tshem tawm maj mam heev thiaj li tsis mus ua puas daim ntawv tseem unfrozen. Tom qab ntawd, koj yuav tsum rov lubricate qhov chaw nrog cov kev daws teeb meem tshwj xeeb.
Tom ntej no, koj yuav tsum pib rov sau dua. Ua li no, ib qho kev sib xyaw ntawm ob lub ntsiab lus silicone sib xyaw ua ntej sib xyaw. Cov kua no yog nchuav rau hauv ib nrab ntawm daim ntawv, uas tseem nyob dawb tom qab plasticine.
Tom qab ua tiav cov kev ua haujlwm tau piav qhia saum toj no, nws raug nquahu kom tawm hauv daim ntawv kom tawv rau tsawg kawg 24 teev. Tom qab lub sijhawm no, nws tuaj yeem qhib thiab tus qauv tshem tawm.
Vim qhov txheej txheem no tau tsim los ua cov pwm sib cais, raws li qhov tshwm sim ntawm kev ua, peb tau txais ob qhov chaw uas yuav tsum tau muab khi ua ke. Ua li no, lub resulting halves ntawm daim ntawv yuav tsum tau folded ua ke. Cov ntsiab lus sib txuas yuav tsum sib phim raws cov npoo. Koj tuaj yeem muab cov hlua khi li no nrog cov khoom tsim tshwj xeeb, siv quav ciab lossis kua yas.
Ntxiv cia
Silicone pwm yog rov siv tau. Txawm li cas los xij, muaj cov kev cai tshwj xeeb rau lawv qhov chaw cia. Yog tias khaws cia rau lub sijhawm ntev lossis qhov kub thiab txias, nws yog ib qho tsim nyog yuav tsum khaws cov pwm silicone hauv chav sov li nees nkaum plaub teev. Tam sim no lawv tau npaj txhij los ua haujlwm rau nchuav gypsum lossis lwm yam khoom xyaw.
Matrix ua siv cov thev naus laus zis no tuaj yeemthov rov ua dua. Koj tau paub txog yuav ua li cas ua silicone rau pwm nrog koj tus kheej tes. Yog tias cov txheej txheem zoo li siv sijhawm ntev rau koj, ces cov qauv zoo li no tuaj yeem yuav ntawm lub khw tshwj xeeb. Feem ntau cov chaw tsim kho yog koom nrog lawv cov muag. Ntxiv mus, silicone, tus nqi ntawm cov khoom los ntawm uas tsis yog siab heev piv rau tus kheej-ua sawv daws yuav, yuav tsis txawv qhov zoo ntawm matrices ua nyob rau hauv tsev. Nyob ntawm seb qhov loj me thiab cov khoom dab tsi cov pwm tsim nyog rau kev nchuav, lawv tus nqi tuaj yeem pib ntawm 50 rubles. per yam.
