Kev tsim cov paving slabs, xab npum souvenir, hniav nyiaj hniav kub thiab bijouterie, ua noj ua haus thiab cosmetology, kev lag luam khoom noj khoom haus thiab kev tsim kho - thiab qhov no yog ib daim ntawv teev npe tsis tiav ntawm cov ntawv thov ntawm silicone roj hmab. Ua ntej yuav mus rau cov zaub mov txawv rau nws tus kheej tsim ib qho analogue ntawm elastic polymers uas tsim los ntawm cov tuam txhab, cia peb nco qab lawv qhov zoo.
Moulding Resins
Universal khoom yog tau los ntawm dissolving crushed quartz nrog nitric acid. Thaum tov nrog ib qho ntawm cov catalysts, nws me ntsis zoo li roj hmab. Cov khoom yog non-toxic, resistant rau alkalis thiab acids. Nyob rau hauv daim ntawv tiav, nws muaj elasticity, cuam tshuam tsis kam, dej kuj thiab unlimited kev pab cuam lub neej. Nws yooj yim heev rau tu cov khoom tsim los ntawm nws, lawv yooj yim khaws cia.
Raws li lub hom phiaj, ob lub ntsiab lus sib xyaw ua ke uas muaj cov tshuaj txhuam thiab cov tawv tawv tau muab faib ua filling, txheej, thiab tseem silicone ua pwm. Nrog koj tus kheej txhais tes, koj tuaj yeem ua los ntawm cov khoom sib xyaw no tsis yog tsuas yog qhov khoob rau cov xab npum zoo nkauj xwb, tab sis kuj muaj cov qauv zoo rau kev nchuav.paving slabs, tau txais cov pob zeb zoo nkauj thiab gypsum moldings.
Txhawm rau muab cov khoom muaj zog, nws yog tov nrog cov tin lossis platinum catalyst, uas muaj nyob rau hauv cov khoom siv, ua ntej siv. Qee qhov zoo ntawm cov roj hmab elastic nyob ntawm seb hom hardener:
- pob tshab lossis haze;
- kua muag los yog lub zog tsim kua muag;
- dimensional stability thiab kub tsis kam;
- hardness;
- sijhawm kawg;
- durability thiab ncig stability.
Piv txwv li, sib tov nrog cov tin catalysts yog siv hauv kev lag luam thiab kev tsim kho. Rau kev tsim cov pob zeb dag lossis cov khoom yas muaj zog, cov khoom siv ruaj khov tshaj plaws yog xav tau. Khoom noj khoom haus qib silicone rau kev tsim cov pwm rau hauv cov qhob noom xim kasfes thiab caramel yog tsim los ntawm platinum hardeners. Lub softness thiab elasticity ntawm cov tebchaw yog tsim nyog rau "qab zib" industries thiab ci.
Qhov twg siv cov polymer hauv tsev
Txawm hais tias muaj ntau yam khoom sib txuas ntawm kev muag khoom, qee tus kws ua haujlwm nyiam ua txhua yam ntawm lawv tus kheej. Qhov no feem ntau yog tsim nyog los ntawm kev txuag nyiaj thiab muaj tswv yim.
Ua silicone rau pwm nrog koj tus kheej tes yog ua tau rau ntau txoj hauv kev. Nws yuav tsum tau muab sau tseg tias qhov tshwm sim cov khoom sib txawv nyob rau hauv cov yam ntxwv los ntawm industrial mixs. Thiab cov kev sib txawv no tsis yog ib txwm zoo. Yog tias cov khoom lag luam ua kua silicone ua cov pwm siv los tsim cov khoom loj thiab me, cesCov roj hmab hauv tsev tsuas yog ua rau cov khoom siv hauv tsev xwb.
Yuav ua li cas los tsim ib tug casting matrix: ib co tswv yim
Pib ua silicone rau pwm nrog koj tus kheej tes, muab lub thawv, lub thawv lossis lub thawv rau kev ua haujlwm tseem ceeb. Nws yog ua los ntawm cov duab los qhia (yog tias cov qauv me me), ntoo lossis yas. Nws tuaj yeem yog collapsible lossis khov. Los ntawm thawj zaug nws yog qhov yooj yim dua los tso cov khoom ua haujlwm khov. Yuav tsum tsis muaj qhov sib txawv ntawm qhov chaw ntawm lub thawv, vim txhua hom elastic muaj fluidity.
Ua ntej koj muab "tus qauv" rau hauv lub thawv, nws tau npog nrog lub tshuab cais. Cov roj nplua nyeem no yuav tsum yog siv quav ciab, roj lossis xab npum. Yuav kom tau txais ib lub matrix rau ib qho khoom plig ntsug, nws txuas rau hauv qab ntawm lub thawv los ntawm kev txhawb nqa ntawm ib daim ntawm plasticine kom nws tsis ntab. Tom qab ntawd, lub pre-mixed compound yog poured nyob ib ncig ntawm tus qauv nyob rau hauv ib tug nyias kwj. Sau lub thawv pib los ntawm cov ces kaum, npog tag nrho cov duab ntsia sab hauv.
Recipe 1: Prep
Yog tias koj xav tau me me ntawm elastic rau cov khoom me, koj tuaj yeem siv ib qho ntawm cov kev xaiv hauv qab no. Ua silicone rau pwm nyob rau hauv tsev pib nrog kev npaj ntawm ib lub tais, ib tug spatula rau nplawm, Cheebtsam, lub ntsiab thawv rau pouring thiab ib tug me me souvenir, lub thiaj li hu ua master figurine, ib tug cam khwb cia ntawm uas yog npaj yuav tau txais rau cloning.”.
Rau thawj txoj kev, glycerin thiabgelatin thiab muab tso rau hauv ib lub thawv me me. Cov muaj pes tsawg leeg yog yaj nyob rau hauv ib da dej nrog tas li stirring, tsis txhob boiling. Cua sov kav 10-12 feeb.
Recipe details 1
Hauv qab ntawm lub tais npaj ua los ntawm cov duab los yog ntoo yog sib npaug nrog cov txiaj ntsig sib xyaw. Tom qab ntawd lub souvenir yog dipped nyob rau hauv tsev silicone thiab sai sai muab tso rau hauv lub thawv no. Cov nplaum nplaum yog tam sim ntawd nchuav nrog kub muaj pes tsawg leeg, sau lub tais rau lub brim.
Ua kua silicone ua pwm, tau los ntawm txoj kev yooj yim, tawv hauv ob peb feeb, yuav luag ua ntej peb ob lub qhov muag. Tom qab cov huab hwm coj tau txias tag lawm, qhov tshwm sim tau raug tshem tawm ntawm lub thawv, txiav yog ua los ntawm sab hauv qab thiab cov khoom plig tau ua tib zoo tshem tawm.
Qhov tshwm sim curly kab noj hniav tsuas yog sau nrog epoxy. Ua silicone rau pwm nrog koj tus kheej txhais tes raws li daim ntawv qhia no muaj ntau qhov tsis zoo:
- cov khoom tiav tiav nqus dej, yog li nws tsis tuaj yeem siv los ua plaster casts;
- Qhov loj melts thaum sim sau cov khoom kub, yog li nws tsis haum rau kev tsim cov xab npum.
- tom qab siv ntau yam, sab hauv ntawm pwm deteriorates, poob nws gloss thiab zoo.
A ntxiv yog lub peev xwm rov ua dua qub qub.
Recipe 2: kev npaj
Ua cov pwm silicone nrog koj tus kheej txhais tes yuav tsum tau siv zog. Masters ua hauj lwm nrog yas av nplaum ua qauv thiab pwm nyob rau hauv no txoj kev,coj koj lub tswv yim mus rau lub neej. Yog li ntawd, koj yuav xav tau ib yam ntawm cov high-temperature-resistant tsev sealant thiab zoo tib yam cov khoom noj starch los yog talc. Nws raug nquahu kom ua haujlwm nrog cov hnab looj tes roj hmab. Txij li thaum lub sealant teem nyob rau hauv 10 feeb, nws yog ib qhov tsim nyog yuav tsum tau muab ib yam khoom nyob ib sab ntawm nws los ntawm cov cam khwb cia yuav npaj: ib lub plhaub, ib daim duab uas yog tiaj tus ntawm ib sab, lwm yam. Cov pwm yuav tig tawm nyuaj, nrog rau qhov chaw ua haujlwm concave, yog li nws tsim nyog rau kev tsim khoom ntawm ib sab xwb.
Recipe 2: details
- Txau me ntsis talc lossis hmoov txhuv nplej siab rau saum lub rooj (kom tiv thaiv tau nplaum).
- Ib pawg ntawm cov sealant yog nyem tawm ntawm lub raj mus rau hauv nruab nrab ntawm lub sprinkle.
- Starch ntxiv rau saum thiab txhua yam sib xyaw.
- Qhov tshwm sim "khoom noj" yuav tsum noj cov hmoov txhuv nplej siab kom tsis txhob lo ntawm tes thiab lub rooj.
- Qhov loj yog siv los ua lub ncuav mog qab zib tuab sib haum rau qhov loj ntawm lub neej tom ntej.
- nrawm thiab raug, cov qauv xaiv raug nias rau hauv qhov khoob no nrog quab yuam.
- Cov pwm ua silicone yog sab laug kom qhuav ib hmos.
- Tom qab tshem cov duab, cov kab noj hniav ntawm cov qauv yog smeared nrog talcum hmoov nrog txhuam thiab nruj nreem ntim nrog cov av nplaum yas.
- lub hauv paus no tuaj yeem muab tso rau hauv qhov cub kom qhuav nrog rau qhov muab tub lim, nws tsis ntshai kub.
Yuav ua li cas thiaj zoo
Thawj qhov zoo yog qhov rov siv tau ntawm cov qauv tsim. Cov khoom khaws cia tag nrho nws qhov zoo. Hauv pwmua los ntawm cov hmoov txhuv nplej siab thiab lub tsev sealant, koj tuaj yeem sau cov xab npum kub, tom qab txau nrog cawv los ntawm lub raj mis tsuag. Xuas tes ua silicone rau pwm ua kom tiv taus qhov kub thiab txias ntawm qhov sib npaug nrog cov qauv tsim.
Ntawm cov minuses yog qhov ntse acetic tsis hnov tsw ntawm sealants thiab ceev ceev solidification ntawm "dough". Tab sis tus tswv tuaj yeem npaj cov khoom lag luam uas xav tau ntawm lub sijhawm tshwj xeeb rau ib txoj haujlwm tshwj xeeb.
