Roj hmab rau Ua nrhiav nrog lawv ob txhais tes nyob rau hauv tsev

Qhuav ntawm paving, souvenir soaps, hniav nyiaj hniav kub thiab costume hniav nyiaj hniav kub, ua noj ua haus thiab cosmetology, khoom noj khoom haus kev lag luam thiab kev tsim kho - thiab qhov no yog ib tug ib nrab daim ntawv teev cov kev siv silicone roj hmab. Ua ntej cov tswv yim kom tau tshuaj ywj siab analog ua los ntawm manufacturers ntawm elastic polymers, peb rov qab lawv zoo.

txoj kev polymers

Universal cov ntaub ntawv uas yog npaj los ntawm dissolving particulate silica nitric acid. Thaum tov nrog ib tug ntawm cov catalysts nws dog dig tsa roj hmab. Cov tshuaj yeeb dej caw yog uas tsis yog-tshuaj lom, resistant rau alkalis thiab acids. Lub tiav lawm khoom muaj elasticity, tej yam kuj, dej kuj thiab ib tug unlimited kev pab cuam lub neej. Rau cov khoom uas ua los ntawm nws yog heev yooj yim mus tu, lawv cia li muab khaws cia.

By lub sij hawm ob-tivthaiv lub tebchaw uas muaj muab tshuaj txhuam thiab hardener, yog muab faib ua casting, obmazochnye thiab silicone ua molds. Nws ob txhais tes yuav ua los ntawm cov mixtures yog tsis tsuas teb rau souvenir xab npum, tab sis kuj khov kho templates sau lub paving slabs, ua hniav pob zeb thiab plaster mouldings.

Yuav ua qhov teeb meem nws ua ntej siv cov khoom hauv lub xeev tov nrog tin los yog platinum catalyst, uas yog txuas nyob rau hauv cov khoom siv. Nyob rau hauv hom hardener nyob ntawm ib co zoo elastic roj hmab:

• Ib tug tshab los yog opaque;
• rhuav lub zog los yog kev sib tawg;
• seem stability thiab tshav kub tsis kam;
• hardness;
• lub sij hawm ntawm kawg solidification;
• durability thiab tirazheustoychivost.

Piv txwv li, ib tug sib tov nrog tin catalysts siv nyob rau hauv kev lag luam thiab kev tsim kho. Zus tau tej cov dag pob zeb los yog ib qho nyuaj yas khoom yuav tsum tau lub feem ntau cov khoom ruaj ruaj. Khoom noj khoom haus-qib silicone pwm, uas yog lawm ua tus sau nrog chocolate thiab caramel, ua rau lub hauv paus ntawm platinum hardeners. Softness thiab elasticity ntawm cov tebchaw yog tsim rau lub "qab zib" thiab ci industries.

Qhov twg qhob polymer siv

Dua li ntawm qhov ntau yam ntawm tebchaw muag muaj, ib txhia craftsmen xav ua tag nrho rau koj tus kheej. Feem ntau, nws yog txoj kev txaus cai los ntawm nqi nyiaj thiab muaj tswv yim mus kom ze rau ua lag ua luam.

Roj hmab rau Ua nrhiav nrog lawv ob txhais tes tau nyob rau hauv ob peb txoj kev. Nws yuav tsum tau clarified tias cov tshuaj yeeb dej caw tau raws nyob rau hauv cov yam ntxwv ntawm muaj mixtures. Thiab tsis yeej ib txwm, cov kev txawv no zoo. Yog hais tias cov neeg kua silicone ua tuaj pwm siv los tsim loj thiab me me khoom uas ua rau ib tug hauv tsev roj hmab rau tsev neeg ua hauj lwm.

Yuav ua li cas rau tsim ib tug qauv rau cov cam khwb cia: ib co tswv yim

Txij li thaum lub zus tau tej cov silicone tsim lawv tus kheej txhais tes, muab tso rau ib lub taub ntim, thawv los yog crate rau cov lag luam. Nws yog ua los ntawm cov duab los qhia (yog hais tias tus qauv yog me me), ntoo los yog yas. Nws yuav ua tau collapsible los yog khoom. Los ntawm cov thawj khov billet yooj yim tso tawm. Nruab nrab ntawm lub thawv qhov chaw yuav tsum tsis txhob yuav muaj slits, txij li thaum tag nrho cov hom ntawm elastics muaj fluidity.

Ua ntej koj yuav muab tso rau lub "qauv" ntawm lub thawv, nws npog separator. Qhov no roj yuav tsum waxy, fatty los yog xub npus. Yuav kom muab tau cov matrix rau lub ntsug souvenir, nws yog txuas mus rau txoj kev muag zaub ntawm lub thawv hauv qab rau ib daim ntawm cov av nplaum uas tsis pop up. Ces ncuav nyob rau hauv ib tug nyias kwj nyob ib ncig ntawm lub qauv pre-kneaded compound. tank filling pib mus rau lub ces kaum, yuav tsum vov tag nrho cov txheej hauv daim duab.

Daim ntawv qhia №1: pre-kev kho mob

Yog hais tias koj xav tau ib tug me me npaum li cas ntawm elastic roj hmab rau ib co me me khoom, koj yuav tau siv ib qho ntawm cov nram qab no kev xaiv. Siv ntawm silicone tsim nyob rau hauv lub tsev pib nrog qhov kev npaj txog ntsha, ib tug duav stirring, ntawm lub Cheebtsam ntawm lub ntsiab thawv rau pouring thiab ib tug me me souvenir, ib tug thiaj li hu ua tswv-nuj nqis, uas yog tau teem tseg tau txais ib tug cam khwb cia rau "cloning".

Rau cov thawj txoj kev coj nyob rau hauv sib npaug zos nqi thiab glycerol gelatin thiab muab tso rau hauv ib tug me me ntim. Muaj pes tsawg leeg yog melted nyob rau hauv ib tug dej da dej nrog rau qhov stirring, tiv thaiv ib kub npau npau. Cov cua kub kav 10-12 feeb.

Paub meej tshuaj №1

Lub hauv qab ntawm lub tais npaj los ntawm cov duab los qhia los yog ntoo uniformly coated nrog lub sib tov. Ces souvenir dipped nyob rau hauv cov qhob silicone thiab sai sai muab tso rau hauv lub npov no. Daim duab adhered tam sim ntawd kub muaj pes tsawg leeg yog poured, sau lub tais mus rau lub brim.

Kua silicone pwm tau nyob rau hauv no txoj kev unpretentious hardens nyob rau hauv ib tug ob peb feeb, suab mus rau lub ob lub qhov muag. Tom qab ua tiav txias ntawm lub loj tau yog muab tshem tawm los ntawm lub thawv bar, ua tus txiav los ntawm lub qis sab thiab meej coj tawm ib tug souvenir.

Cov uas ua figured kab noj hniav yuav tsum tau sau tsuas nrog epoxy cob. Roj hmab rau Ua nrhiav nrog lawv txhais tes rau ntawm no daim ntawv qhia muaj ib tug ob peb drawbacks:

• npaj tswv khoom absorbs dej, ces nws yuav siv tsis tau rau plaster ntiab;
• loj melts thaum sim mus sau ib tug kub tshuaj, yog li ntawd tsis haum rau lub creation ntawm designer xab npum.
• tom qab ib tug ob peb siv lub puab nto pwm deteriorates, loses ci thiab zoo.

Plus muaj peev xwm pom tau hais tias ntau yam remelting hauj lwm pab lawv nyiaj muas.

Daim ntawv qhia №2: npaj

Siv ntawm silicone tsim lawv tus kheej txhais tes yuav tsum tau siv zog. Craftsmen ua hauj lwm nrog yas av nplaum, ua li no Pwm thiab cov qauv rau kev lawv cov tswv yim. Yog li ntawd, koj xav tau ib tug yam ntawm kub resistant siv sealants thiab cov zaub mov hmoov txhuv nplej los yog talc. Nws yog ib advisable mus ua hauj lwm nyob rau hauv roj hmab hnab looj tes. Txij li thaum lub sealant chaw tshwm sim tsis pub dhau 10 feeb kindly thov kom muab tso rau tom ntej no rau tus kwv uas mus npaj cov cam khwb cia ntawm: plhaub, ncaj nraim rau ib sab ib daim duab, ib yam dab tsi txawv. Pwm tig khoom, nrog ib tug concave kev nyuaj siab, ces nws yog haum rau zus tau tej cov ib leeg-tog xwb souvenirs.

Daim ntawv qhia №2: cov ntsiab lus

1. Nyob rau saum npoo ntawm lub rooj poured ib tug me ntsis talcum hmoov los yog hmoov txhuv nplej (tsis daig).
2. Nyob rau hauv lub center ntawm kis tus kab mob squeezed los ntawm ib tug raj pawg sealant.
3. Starch los ntawm saum toj no ntxiv thiab tov.
4. Cov uas ua "xeem" yuav tsum noj kom ntau li ntau cov hmoov txhuv nplej uas yog tsis daig rau ob txhais tes thiab mus rau lub rooj.
5. Ntawm qhov ceeb thawj ua ib tug tuab wafer, sib nug xov mus rau lub qhov ntev ntawm lub neej yav tom ntej souvenir.
6. Sai sai thiab meej, nrog quab yuam nias rau hauv lub preform xaiv qauv.
7. Silicone pwm siab yog sab laug mus rau qhuav rau ib hnub twg.
8. Tom qab extraction cov kab noj hniav yog lubricated nrog talc daim duab template siv ib tug txhuam hniav thiab tightly tau ntim yas av nplaum.
9. Xws li ib tug lub moj khaum yuav tsum muab tso rau hauv lub qhov cub kom qhuav ua ke nrog ib tug tub lim, nws tsis yog ntshai ntawm kub.

Yuav ua li cas yog qhov zoo txog cov qauv no

Tus thawj ntawm qhov zoo tej zaum yuav tau hais ib tug reusable template tau. Cov khoom retains tag nrho nws cov qualities. Nyob rau hauv Pwm ua los ntawm cov hmoov txhuv nplej thiab ib tug kev tsim kho sealant yuav poured kub xab npum puag, haus dej cawv ua ntej sprinkled los ntawm cov tshuaj tsuag. Silicones ua tuaj pwm, ua los ntawm lawv tus kheej txhais tes, muaj peev xwm mas thermal kev nyuaj siab nyob rau hauv ib tug par uas muaj lug.

Ntawm cov disadvantages xa ntse tsw acetic sealants thiab ceev ceev solidification "ua khob noom cookie". Es tsis txhob, lub wizard yuav npaj ib tug xov tooj ntawm tej yam uas yuav tsum tau precisely ntawm ib lub sij hawm rau ib qho hauj lwm.
