Khoom Taw Qhia thiab Nta

Cov siv ua pa ua ke, tseem yog ib hom crystal siv quav ciab, yog ib hom solubofac, carbon tetrachlents, carbon tetrachlents, carbon tetrachlents, insollule hauv dej thiab methanol thiab lwm yam kuab tshuaj.

kev siv

Crude paraffin yog tsuas yog siv nyob rau hauv kev tsim cov ntais ntawv, fiberyboard thiab cov ntaub ntawv canvas vim nws cov ntsiab lus roj siab. Tom qab ntxiv polyolefin ntxiv rau cov paraffin, nws cov nplaum thiab cov duab kos duab thiab cov duab los qhia txog cov khoom siv hluav taws xob thiab cov tswm ciab.
Daim ntawv raus dej nyob rau hauv paraffin siv quav ciab tuaj yeem npaj nrog kev ua dej tsis zoo ntawm ntau daim ntawv ciab Thaum paraaffin ntxiv rau paj paj paj rwb, nws tuaj yeem ua rau textile mos, du thiab Elastic. Paraffin kuj tseem tuaj yeem ua cov tshuaj ntxuav tes, emulsifier, dispersant, yasizer, roj, thiab lwm yam.
Tag nrho cov tshuaj Paraffin thiab cov khoom siv ua kom dav dav siv, feem ntau yog cov khoom siv hauv cov khoom noj, xws li cov ntaub ntawv ntim khoom noj rau cov khoom noj, rau cov txiv ntoo kom ceev [3], rau rwb thaiv tsev ntawm cov hluav taws xob Cheebtsam, thiab rau kev txhim kho cov kev laus laus thiab yooj ntawm roj hmab [4]. Nws kuj tseem siv tau rau oxidation los tsim cov hluavtaws fatty acids.
Raws li ib hom ntawm Latent Thaum Tshav Kub Kub Khoom Siv Khoom Siv Hluav Taws Xob, kev hloov pauv me me thaum lub sijhawm hloov pauv, tsis muaj qhov tshwm sim hauv theem, tsis muaj nqi hauv qab, tus nqi qis thiab lwm yam. Ib qho ntxiv, kev txhim kho ntawm aviation, Aetostertrace, microostronics ntau zaus yuav tsum tau dissipated nyob rau hauv ib qho kev tiv thaiv tshav kub dissipation thiab lub sijhawm luv heev, thaum tsawg Melting taw tes hloov cov khoom tuaj yeem ncav cuag tau sai sai ntawm lub ntsiab lus hloov theem, thiab ua kom muaj cua sov li latent kom ua tiav kub. Lub luv luv luv thermal teb lub sijhawm ntawm paraffin tau siv dav hauv ntau thaj teb, ib qho kev siv hluav taws xob, microelectronic, microelectronics thiab lwm yam high-tech systems raws li lub tsev txuag vaj tse. [5]
GB 2760-96 tso cai rau kev siv cov pos hniav hauv qab zib tus neeg sawv cev, qhov kev txwv yog 50.0g / kg. Txawv Teb Chaws tseem siv rau cov ntawv nplaum nplej ua ntau lawm, cov tshuaj ntawm 6g / kg. Ib qho ntxiv, nws tseem muaj dav siv hauv cov ntaub ntawv ntim khoom noj, xws li ya kom muaj noo-pov thawj, tiv thaiv thiab roj-pov thawj. Nws yog qhov haum rau cov zaub mov zom zom, npuas bubbum thiab tshuaj zoo roj kub thiab cov ntsiav tshuaj ncaj qha rau hauv cov zaub mov thiab tshuaj (cov roj av los ntawm Cov xovxwm no thiab lwm txoj kev).

Pob Thiab Thauj

B. Cov khoom lag luam no tuaj yeem siv ,, 25kg, 200kg, 1000kgbaerls.
C. Cov khw ntim khoom txias rau hauv qhov chaw txias, qhuav thiab muaj qhov cua nyob sab hauv tsev. Cov ntim yuav tsum kaw kom nruj nreem tom qab siv ua ntej siv.
D. Cov khoom no yuav tsum tau muab kaw zoo thaum caij tsheb thauj mus los kom tiv thaiv noo noo, muaj zog alkali, nag, nag los ntawm kev sib xyaw.
