Taw qhia
BENZOIN yog ib qho resin uas tau siv rau ntau lub hom phiaj txij thaum ub los. Cov hauv qab no yog cov lus piav qhia ntawm qhov xwm txheej, kev siv, kev npaj thiab kev nyab xeeb ntawm BENZOIN:
Xwm:
1. Cov tsos mob: BENZOIN yog cov khoom daj mus rau xim liab, qee zaum nws tuaj yeem ua pob tshab.
2. Cov ntxhiab tsw: Nws muaj cov ntxhiab tsw tshwj xeeb thiab tau siv dav hauv kev lag luam tshuaj tsw qab thiab naj hoom.
3. Ceev: qhov ceev ntawm BENZOIN yog li ntawm 1.05-1.10g / cm³.
4. Melting Point: nyob rau hauv lub melting point range, BENZOIN yuav ua viscous.
Siv:
1. Cov txuj lom: BENZOIN tuaj yeem siv los ua cov txuj lom ntuj, siv los ua txhua yam tshuaj tsw qab, tshuaj tsw qab thiab tshuaj tsw qab.
2. Tshuaj: BENZOIN yog siv los kho cov tsos mob xws li hnoos, mob ntsws thiab mob plab.
3. Kev lag luam: BENZOIN yog siv los ua cov nplaum, coatings, sealants thiab roj hmab additives.
4. Kev siv kab lis kev cai thiab kev cai dab qhuas: BENZOIN feem ntau siv rau hauv kev cai dab qhuas thiab kev coj noj coj ua xws li kev txi, hluav taws kub hnyiab thiab kev cog lus ntawm sab ntsuj plig.
Txoj Kev Npaj:
1. Txiav los ntawm cov ntoo mastic: Txiav ib qho me me ntawm cov ntoo ntawm cov ntoo mastic, cia cov kua resin ntws tawm, thiab cia nws qhuav los ua BENZOIN.
2. Txoj kev Distillation: Thaum tshav kub kub ntawm cov pos hniav thiab resin ntawm cov pos hniav mus rau qhov kub siab tshaj qhov kub ntawm cov pos hniav ntawm mastic, boil nws thiab distilled nws, thiab thaum kawg tau BENZOIN.
Cov ntaub ntawv kev nyab xeeb:
1. Cov resin ntawm tsob ntoo mastic tej zaum yuav muaj kev tsis haum rau qee tus neeg, yog li yuav tsum tau ua qhov kev ntsuam xyuas ntawm daim tawv nqaij ua ntej siv.
2. Cov resin ntawm mastic ntoo yog suav hais tias yog ib yam khoom muaj kev nyab xeeb heev, tsis muaj qhov pom tseeb toxicity lossis carcinogenic.
3. Thaum hlawv xyab, ua tib zoo saib xyuas kev tiv thaiv hluav taws kom tsis txhob muaj hluav taws kub.
4. Hauv kev siv BENZOIN, yuav tsum ua raws li cov lus qhia kev nyab xeeb thiab kev cia khoom tsim nyog, tiv thaiv kev noj, tiv thaiv qhov muag lossis nqus pa.
Nws yuav tsum raug sau tseg tias cov ntaub ntawv saum toj no tsuas yog siv rau kev siv xwb. Yog xav tau kev taw qhia ntxaws lossis kev tshawb fawb ntxiv, nws raug nquahu kom sab laj nrog kws kho mob lossis kws muag tshuaj.
