Cov kws tsim khoom siv tes ua yuav pom "mis nyuj-pob zeb" zoo heev, lom zem heev. Muaj kev lom zem nrog yas/pob zeb. Hu ua Galalith, galalithite, lossis Erinoid (hauv tebchaws Askiv) lossis "mis nyuj pob zeb", tau tsim tawm xyoo 1898 thiab siv dhau xyoo 1930 los ua yas lossis pob zeb los ua khawm, cov hniav nyiaj hniav kub, khoom siv hauv tsev lossis chaw ua haujlwm. Cov tshuaj polymer zoo no, yas muaj ntau qhov zoo: nws yooj yim, tsis muaj tshuaj lom, ib zaug tawv: tiv thaiv kev ua xua, biodegradable, antistatic.
Cov kauj ruam
Kauj Ruam 1. Ntsuas lub khob ntawm cov mis tsis muaj rog rau hauv lub lauj kaub (tuaj yeem ua butter los ntawm cov mis nyuj tag nrho, tom qab ntawd siv cov whey rau txoj haujlwm no) txhawm rau sim nrog thiab ua kom sov kom txog thaum nws yaj; do kom tsis txhob kub hnyiab; pub me ntsis ua npuas ib ncig ntawm ntug
Tsis txhob ua npuas ntau dhau los ntawm kev ua kom sov. Los yog, sov nws hauv lub tais hauv microwave microwave (pib qis dua thiab ntxiv sijhawm ntxiv, txog li ob feeb, raws li qhov tsim nyog nyob ntawm koj lub microwave).
Kauj Ruam 2. Ncuav rau hauv 1 diav kua txiv hmab txiv ntoo uas siv xab npum, do thiab tos kom muaj cov tshuaj tiv thaiv
Dab tsi tshwm sim yog tias cov kua qaub hauv cov kua txiv hmab txiv ntoo (5% ascetic acid) tab tom cuam tshuam nrog cov tshuaj hauv mis.
Kauj Ruam 3. Ntxiv cov ntawv ci ci lossis lwm yam khoom siv zoo nkauj rau hauv pawg thaum nplawm nws
Kauj Ruam 4. Ntxiv cov zas xim, rau nws lo rau hauv cov ntaub ntub dej yas (pob zeb) lossis tuaj yeem zas xim tom qab
Lossis, ua tib zoo kom muaj xim zoo ib yam
Kauj Ruam 5. Txias nws kom zoo kom xis nyob rau qhov kov:
Tsis txhob kov los yog muab cov khoom los ntim rau thaum nws kub.
Kauj Ruam 6. Nyuaj qeeb kom cais cov coagulated, curdled-milk/casein tawm ntawm cov kua (mis-whey), siv tus colander (tsis txhob nias rau hauv lub colander) lossis zoo li ntawd
Lim cov kua ob zaug lossis ntau dua yog tias xav tau (Siv cov kua qaub txaus, lossis qhov no yuav yog cov cheese thiab cov whey, siv tsuas yog ob peb tee ntawm cov khoom tsis muaj tshuaj lom).
Kauj Ruam 7. Muab cov ntaub ntawv pov tseg tso rau hauv daim ntawv lossis cov ntaub huv hauv chav ua mov, lossis xws li (tsis yog ntaub ntaub)
casein -ca · sein (kā'sēn ', -sē -ĭn) n. Ib qho dawb, tsis qab, tsis muaj cov protein ua los ntawm nyuj cov mis uas yog lub hauv paus ntawm cheese "thiab tau siv los ua cov yas, nplaum, pleev xim, thiab khoom noj"
Kauj Ruam 8. Khaws daim phuam thiab tshem cov kua ntau dhau
Nyem maj mam.
Kauj Ruam 9. Tshaj tawm, tsis thim thiab muab cov curd tso rau ntawm daim ntawv tsim nyog/ntawv ciab thiab muab tso rau kom qhuav - tej zaum npog nws nrog daim ntaub weave qhib kom tsis txhob muaj plua plav thiab khib nyiab
Kauj Ruam 10. Tso cov yas (casein) kom qhuav rau ob peb hnub
Cov yas no yog thermoset, tsis yog cua sov, piv txwv li: yuav tsis yaj vim cua sov.
Kauj Ruam 11. Ua Kom Zoo/Pwm nws los ntawm kev ziab khaub ncaws hauv qee hom, xws li lub raj mis hau, rau nws cov qauv yooj yim lossis ua kom qhuav nws hauv cov ntawv, daim ntawv pas lossis lwm yam
Nws tuaj yeem qhuav hauv qhov yooj yim ntawm cov hniav nyiaj hniav kub thiab ua tiav tom qab.
Dye cov yas nto los ntawm dipping los yog streaking nws nrog dyes lossis zas tuaj yeem tau ntxiv rau hauv kev ua cov ntaub ntub dej yas (s) thiab streak ob lossis ntau xim, thiab lwm yam:
xim thoob plaws, hauv streaks lossis tsuas yog nqus rau hauv cov pob zeb qhuav.
Ua haujlwm cov khoom thaum qhuav:
Nws nyhav rau warp thaum ziab. Nws yog nkig, ua tsis khoov ib zaug qhuav.
Rov ua dua thiab ua tiav cov mis nyuj-pob zeb:
carving, etching, txiav, sanding, drilling, polishing, thiab lwm yam los ua koj cov khoom.
Ua cov khoom siv mis nyuj-pob zeb thiab cov khoom lag luam:
cov nyees khawm, cov hniav nyiaj hniav kub, hauv tsev, chav dej lossis khoom siv hauv chaw ua haujlwm.
Kauj Ruam 12. Nyuaj rau cov yas (xaiv tau) thaum qhuav los ntawm raus nws hauv formaldehyde thiab rov ua kom qhuav
Qhov no yog cov khoom ntxeem tau, nws mus ntau dua qhov tob.
Qhov no ntxiv dag zog rau nws, muab kev tiv thaiv rau khawb thiab hnav ntev dua
Kauj Ruam 13. Ceev faj:
Siv cov qhov tso pa kom txaus raws li formaldehyde yog cov tshuaj carcinogenic paub; yog li tsis txhob nqus nws cov pa, tiv thaiv koj cov tawv nqaij, thiab qhov muag, thiab lwm yam. Yog tias nws raug hu, ntxuav tawm thaj chaw uas cuam tshuam, piv txwv li: yaug qhov muag rau kaum tsib (15) feeb yog tias txaws lossis hu rau hauv qhov muag. Yog tias nqos tau hu rau koj lub chaw saib xyuas kev kho mob seb yuav ua li cas, xws li Lub Chaw rau Kev Tswj Tshuaj Lom rau cov ntaub ntawv.
Kauj Ruam 14. Tiav lawm
Yees duab - Los ntawm kev siv qhov kev pabcuam no, qee cov ntaub ntawv yuav raug muab qhia rau YouTube
Lub tswv yim
- Nov yog qhov kev sim tshawb fawb zoo los ua tom tsev thaum koj tsis muaj dab tsi ntxiv los ua.
- Yog tias koj nyiam pranks, nchuav cov dej sov sov rau hauv lub jug lossis thawv, tshem tawm cov whey, thiab cia nws zaum kom qhuav li ob peb hnub kom nws yuav tig mus rau pob zeb/mis nyuj tawv dhau sijhawm. Tus neeg uas sim nchuav cov mis thaum koj muab tso rov qab rau hauv lub tub yees yuav pom qhov xav tsis thoob.
- Ua cheese nrog tsawg acid: Raws li txheej txheem ib sab, yog tias qhov no tau ua tiav nrog cov kua txiv qaub lossis txiv qaub, lossis lwm yam kua txiv hmab txiv ntoo, lossis tsuas yog dauv cov kua txiv hmab txiv ntoo nws yuav ua cov khoom cheese. Kev ua kom sov txaus yuav ua rau Pasteurization kom huv. Koj tuaj yeem haus whey. Kho cov cheese.
- Cov neeg siv khoom tsim khoom raug tso tseg los ntawm kev faib tawm hauv Kev Tsov Rog Ntiaj Teb Zaum II thiab tom qab pom los ntawm cov khoom siv hluavtaws yas.
Lus ceeb toom
- Ceev faj nrog cua sov thiab nrog cov khoom siv ua kom sov.
- Formaldehyde yog teeb meem tab sis tsis yog ib yam nkaus li tau siv ntev ntev los khaws cia cov kev sim hauv ntiaj teb cua nab thiab tsiaj txhu rau kev tshuaj xyuas kab mob hauv lub cev thiab lwm yam kev sim.
- Formaldehyde yuav ua rau mob qog noj ntshav thiab ua pa nyuaj
Yam Uas Koj Yuav Tsum Muaj
- Ntsuas khob
- Ntsuas/nplawm rab diav
- Mis (tsis muaj rog, tsis muaj rog, skimmed)
- Dawb vinegar
- Pan, los yog lub tais
- Ntawv los yog daim ntaub mos mos
- Cua sov qhov chaw
- Qhov chaw ziab khaub ncaws
- Formaldehyde (Tsis teb los tau)
- Dyes (Tsis teb los tau)
- Cov khoom thiab cov hlua ntawm cov khoom siv kom zoo nkauj ntxiv (Tsis teb los tau)
