Dimethyl Formamide / DMF Ruaj khov zoo thiab sib tw nqi
Daim Ntawv Thov
Dimethyl formamide (DMF) yog ib yam khoom siv tshuaj lom neeg tseem ceeb thiab cov kuab tshuaj zoo heev, feem ntau yog siv rau hauv polyurethane, acrylic, tshuaj, tshuaj tua kab, dyes, electronics thiab lwm yam lag luam. Ntxuav hauv kev lag luam polyurethane ua tus neeg sawv cev kho, feem ntau yog siv rau kev tsim cov tawv nqaij ntub; cov tshuaj synthetic hauv kev lag luam tshuaj ua cov khoom siv nruab nrab, dav siv rau kev npaj cov tshuaj doxycycline, cortisone, sulfa; kev lag luam acrylic lub rooj tsavxwm quenching ua cov kuab tshuaj feem ntau yog siv rau kev tsim cov acrylic qhuav spinning; kev lag luam tshuaj tua kab rau kev tsim cov tshuaj tua kab ua haujlwm siab thiab tsis muaj tshuaj lom; dyes hauv kev lag luam zas xim ua cov kuab tshuaj; cov khoom tinned hauv kev lag luam hluav taws xob ua kev ntxuav, thiab lwm yam; lwm yam lag luam, suav nrog cov neeg nqa cov pa roj txaus ntshai, cov tshuaj siv cov kuab tshuaj crystallization.

Kev Khaws Cia
Vim tias Dimethyl Formamide (DMF) yog cov tshuaj organic uas muaj cov khoom yooj yim hlawv thiab volatile, cov ntsiab lus hauv qab no yuav tsum tau sau tseg thaum khaws cia:
1. Ib puag ncig khaws cia: DMF yuav tsum khaws cia rau hauv qhov chaw txias, qhuav thiab muaj cua nkag tau zoo, tsis txhob raug tshav ntuj ncaj qha thiab kub heev. Qhov chaw khaws cia yuav tsum nyob deb ntawm hluav taws, cua sov thiab oxidant, cov chaw tiv thaiv kev tawg.
2. Kev Ntim Khoom: DMFS yuav tsum khaws cia rau hauv cov thawv uas kaw tau zoo, xws li cov fwj iav, cov fwj yas lossis cov thoob hlau. Yuav tsum tau kuaj xyuas qhov ruaj khov thiab nruj ntawm cov thawv tsis tu ncua.
3. Tiv thaiv kev tsis meej pem: DMF yuav tsum tsis txhob sib xyaw nrog cov tshuaj oxidant muaj zog, cov kua qaub muaj zog, cov hauv paus muaj zog thiab lwm yam tshuaj kom tsis txhob muaj kev phom sij. Thaum khaws cia, thauj khoom, tshem tawm thiab siv, yuav tsum tau ceev faj kom tsis txhob muaj kev sib tsoo, kev sib txhuam thiab kev co, kom tsis txhob muaj kev xau thiab xwm txheej.
4. Tiv thaiv hluav taws xob zoo li qub: Hauv DMF cia, thauj khoom, tshem tawm thiab siv cov txheej txheem, yuav tsum tiv thaiv kev tsim hluav taws xob zoo li qub. Yuav tsum tau ua cov kev ntsuas tsim nyog, xws li kev sib txuas hauv av, txheej, cov khoom siv tiv thaiv hluav taws xob, thiab lwm yam.
5. Kev cim qhia daim ntawv lo: Cov thawv DMF yuav tsum tau cim nrog cov ntawv lo thiab cov cim qhia meej, qhia hnub cia, lub npe, kev sib xyaw, qhov ntau thiab lwm yam ntaub ntawv, kom yooj yim rau kev tswj hwm thiab kev txheeb xyuas.
