Raw khoom yog ib yam khoom uas muab rho tawm los ntawm lub ntiaj teb los yog tsim los ntawm cov nroj tsuag los yog tsiaj txhu uas yog siv nyob rau hauv manufacturing los yog kev tsim kho. Nws yog daim ntawv yooj yim tshaj plaws ntawm cov khoom siv los ua cov khoom tiav.
Hauv tsab xov xwm no, Kuv yuav nkag mus rau qhov nws yog dab tsi, nws siv li cas, thiab nws cuam tshuam li cas rau cov khoom tiav.
Hauv kab ntawv no peb yuav npog:
Raw Khoom: Lub Tsev Blocks ntawm Kev Tsim Khoom
Cov khoom siv raw yog cov khoom siv yooj yim siv hauv kev tsim cov khoom, cov khoom tiav, lub zog, lossis cov khoom nruab nrab uas yog feedstock rau cov khoom tiav yav tom ntej. Hauv lwm lo lus, cov khoom siv raw yog lub tsev tsim khoom. Lawv yog cov khoom tseem ceeb uas cov tuam txhab siv los tsim cov khoom thiab cov kev pabcuam uas peb siv txhua hnub.
Qhov sib txawv ntawm cov khoom siv raw
Muaj ob yam tseem ceeb ntawm cov khoom siv raw: ncaj qha thiab tsis ncaj. Cov khoom siv raw khoom ncaj qha yog cov khoom siv ncaj qha hauv kev tsim cov khoom zoo, thaum cov khoom siv tsis ncaj yog cov khoom siv ncaj qha rau kev tsim cov khoom zoo, tab sis tsim nyog rau cov txheej txheem ntau lawm. Qee qhov piv txwv ntawm cov khoom siv ncaj qha muaj xws li:
- Ntoo rau rooj tog
- Mis rau cheese
- Npuag rau khaub ncaws
- Lumber rau rooj
- Dej rau haus
Indirect raw cov ntaub ntawv, ntawm qhov tod tes, suav nrog cov khoom xws li cov cuab yeej siv thiab tshuab, uas tsim nyog rau cov txheej txheem tsim khoom tab sis tsis ncaj qha mus rau hauv cov khoom kawg.
Lub luag haujlwm ntawm Raw Materials hauv Manufacturing
Cov khoom siv raw yog qhov tseem ceeb hauv kev tsim khoom. Lawv yog cov khoom uas tau muab rho tawm lossis yuav los ntawm kev sib pauv thiab kev lag luam, thiab siv los hloov mus rau cov khoom tiav. Cov ntaub ntawv nyoos raug cais raws li lawv qhov xwm txheej thiab cuam tshuam nrog ntau yam khoom lag luam, suav nrog kev ua liaj ua teb, hav zoov, thiab cov khoom lag luam.
Qhov txawv ntawm Raw Materials thiab Intermediate khoom
Cov khoom siv raw thiab cov khoom nruab nrab feem ntau xav tias yog tib yam, tab sis muaj qhov sib txawv tseem ceeb ntawm ob. Cov khoom siv raw yog cov khoom siv tsis tau siv ncaj qha rau hauv kev tsim cov khoom zoo, thaum cov khoom nruab nrab yog cov khoom siv uas twb tau ua tiav lawm thiab siv los tsim lwm yam khoom. Piv txwv li, ntoo yog cov khoom siv raw siv los tsim cov rooj tog zaum, thaum daim ntawv ntawm cov ntaub yog qhov nruab nrab zoo siv los tsim cov khaub ncaws tiav.
Qhov Nqa Nyiaj

- Cov khoom siv raw khoom ncaj qha yog cov khoom siv ncaj qha hauv kev tsim cov khoom zoo, thaum cov khoom siv tsis ncaj yog cov khoom tsim nyog rau cov txheej txheem tsim khoom tab sis tsis ncaj qha mus rau hauv cov khoom kawg.
- Cov khoom siv raw yog ib qho tseem ceeb hauv kev tsim khoom thiab muaj feem xyuam nrog ntau yam khoom.
- Cov ntaub ntawv nyoos muaj tus nqi nyob ib leeg hauv kev ua lag luam thiab yog qhov tseem ceeb hauv kev txiav txim siab tus nqi ntawm cov khoom muag thiab tus nqi kawg ntawm cov khoom.
- Cov khoom siv raw thiab cov khoom nruab nrab yog qhov sib txawv, nrog rau cov khoom siv raw yog cov khoom siv tsis tau siv ncaj qha rau hauv kev tsim khoom thiab cov khoom nruab nrab yog cov khoom siv los ua lwm yam khoom.
Qhov sib txawv ntawm cov khoom siv ncaj qha thiab tsis ncaj yog qhov tseem ceeb ntawm lawv cov kev cuam tshuam rau cov nqi tsim khoom. Cov khoom siv ncaj qha yog cov khoom lag luam tseem ceeb thiab cuam tshuam ncaj qha rau kev tsim khoom. Lawv raug them raws li tus nqi tsev thiab suav rau hauv tag nrho cov nqi ntawm cov khoom muag. Indirect raw cov ntaub ntawv, ntawm qhov tod tes, raug them raws li cov nqi nyiaj siv ua haujlwm thiab suav rau hauv tag nrho cov nqi ntawm kev tsim khoom.
Kev nkag siab txog qhov sib txawv ntawm cov khoom siv ncaj qha thiab tsis ncaj yog qhov tseem ceeb rau kev suav tag nrho cov nqi ntawm kev tsim khoom thiab muab cov txheej txheem tsim khoom zoo. Txawm hais tias cov khoom siv ncaj qha thiab tsis ncaj ncaj yuav zoo li zoo sib xws, lawv ua lub luag haujlwm sib txawv hauv cov txheej txheem tsim khoom thiab muaj kev faib tawm sib txawv ntawm kev suav nyiaj thiab cov khoom lag luam.
Tshawb nrhiav qhov sib txawv ntawm cov khoom siv raw siv hauv kev tsim khoom
Synthetic raw cov ntaub ntawv yog cov ntaub ntawv uas tsis pom nyob rau hauv cov xwm thiab yog tsim los ntawm ib tug raug kev tsim. Cov ntaub ntawv no yog qhov tseem ceeb hauv kev tsim cov khoom tiav thiab feem ntau siv los ntawm cov khoom siv raw vim lawv cov khoom zoo. Piv txwv ntawm cov khoom siv hluavtaws muaj xws li:
- Glue: siv los khi cov ntaub ntawv ua ke.
- Yas: Siv los ua ntau yam khoom, nrog rau cov khoom ua si, khoom siv hauv tsev, thiab tshuab.

Yog li ntawd, raw cov ntaub ntawv yog lub tsev blocks ntawm ntau lawm. Lawv tau siv los ua cov khoom tiav, xws li khaub ncaws, rooj tog zaum, thiab khoom noj.
Tam sim no koj yuav tsum paub qhov txawv ntawm cov khoom siv raw thiab cov khoom tiav, thiab vim li cas cov ntaub ntawv raw tseem ceeb heev rau kev tsim khoom.
Kuv yog Joost Nusselder, tus tsim ntawm Tools Doctor, cov ntsiab lus lag luam, thiab txiv. Kuv nyiam sim cov cuab yeej tshiab, thiab ua ke nrog kuv pab neeg kuv tau tsim cov ntawv blog tob txij li xyoo 2016 los pab cov neeg nyeem siab ncaj nrog cov cuab yeej & cov lus qhia ua khoom siv.
