Yog hais tias, ntsuas qhov hnyav yog qhov tseeb tshaj plaws. Yog tias koj txiav txim siab sib tov los ntawm qhov hnyav, nco ntsoov qhov ceev ntawm cov resin thiab hardener yog txawv. Qhov no txhais tau tias qhov hnyav ntawm ob yuav sib txawv yog li qhov piv yuav txawv dua li qhov ntim.
Dab tsi yog qhov piv rau kev sib xyaw epoxy?
A 1: 1 ratio txhais tau tias 1 feem ntawm A resin thiab 1 feem ntawm B hardener yog tov ua ke. Cov kev sib piv tshwj xeeb no sib xyaw ua ke tsim cov tshuaj tiv thaiv tshwj xeeb (kev tuav tes molecular) uas ua rau kev sib xyaw ua ke epoxy kho cov khoom. Kev kho mob epoxy nyuaj yog 100% nyob ntawm kev ntsuas kom zoo thiab sib xyaw epoxy.
Kuv puas tuaj yeem sib xyaw epoxy los ntawm qhov hnyav?
Raws li tag nrho cov epoxy resins, peb lub tshuab tau tsim los ua haujlwm hauv qhov sib xyaw tshwj xeeb ntawm ob qhov chaw. Peb CLR epoxy resin nrog CLF Fast Hardener ua haujlwm hauv 100: 47 sib xyaw piv los ntawm qhov hnyav lossis 2: 1 ntim piv.
Koj puas muab cov cob los ntawm qhov hnyav lossis ntim?
Yog hais tias, ntsuas qhov hnyav yog qhov tseeb tshaj plaws. Yog tias koj txiav txim siab sib tov los ntawm qhov hnyav, nco ntsoov qhov ceev ntawm cov resin thiab hardener yog txawv. Qhov no txhais tau tias qhov hnyav ntawm ob yuav sib txawv yog li qhov piv yuav txawv dua li qhov ntim.
Yuav ua li cas yog tias koj muab cov tawv tawv ntau dhau rau hauv cov resin?
Ntxiv ntau dhau ntawm cov resin lossis hardener yuav hloov cov tshuaj tiv thaiv thiab cov sib tov yuav tsis kho kom zoo.

Dab tsi yog qhov ntim ntim ntim ntawm lub raum lub plab?
khaws cov tubules ua rau lub raum lub plab, thaj chaw zoo li lub hauv paus hauv nruab nrab ntawm qhov me me, lub khob zoo li lub raum lub plab yog hu ua calyces lossis calices (singular: lossis calix) . Cov qauv Cuplike pom hauv lub raum plab hu ua dab tsi?
Qhov sib tov twg qhia qhov sib txawv zoo?
C2 H5OH thiab cyclohexane sib xyaw qhia tau tias muaj kev sib txawv ntawm Raoult txoj cai . Qhov twg ntawm qhov sib xyaw hauv qab no qhia qhov sib txawv zoo? Solution: [d] Qhov sib tov of CCl4+CHCl3 qhia qhov sib txawv ntawm qhov zoo ntawm tus cwj pwm zoo .
Ntawm qhov sib npaug ntawm qhov sib npaug ntawm cov reactants) thiab cov khoom) yog qhov tas li?
Nyob rau hauv ib qho tshuaj sib npaug, cov tshuaj tiv thaiv rau pem hauv ntej thiab thim rov qab Cov tshuaj tiv thaiv rov qab yog ib qho reaction uas hloov dua siab tshiab ntawm reactants rau cov khoom thiab hloov cov khoom rau reactants tshwm sim ib txhij … Hauv qhov rov qab cov tshuaj tiv thaiv, hydrogen iodide decomposes rov qab rau hauv hydrogen thiab iodine.
Qhov twg cov twj paj nruag yuav tsum zaum hauv qhov sib tov?
Vim lawv tsis muaj kev taw qhia, thiab vim tias lawv muaj feem ntau ntawm lub zog hauv kev sib xyaw ua ke, nws yog qhov zoo tshaj kom khaws cov suab no nyob rau hauv nruab nrab ntawm koj cov khoom sib xyaw Tsim kom muaj ntuj qhov chaw nyob hauv lub tso suab sib kis rau txhua lub nruas.
Rau cov roj zoo tagnrho uas qhov sib txawv yog qhov sib txawv ntawm qhov sib txawv?
Boyle txoj cai hais tias siab (P) thiab ntim (V) yog qhov sib npaug. Charles txoj cai hais tias ntim (V) thiab qhov kub thiab txias (T) ncaj qha proportional . Txoj cai roj twg yog qhov sib npaug sib npaug? Rau qhov loj ntawm cov roj zoo tagnrho khaws cia ntawm qhov kub thiab txias, siab thiab ntim yog qhov sib npaug.
