Yam ntxawv tshaj plij ntawm cov dej no tseem ceeb tshaj plij yog qhov viscosity. Viscosity txheeb xyuas yuav ua rau dej no tuaj yeem pab sib npaug, khaub ncua, tawm, tso cia, thiab ua haujlwm. Yog tias peb tsis txheeb xyuas viscosity raws li kev xav tau, ces yuav muaj kev puas tsuaj rau cov dej no, kev xaiv tsis zoo rau cov neeg siv, thiab yuav tsum ua dua kom zoo, uas yuav ua rau khoom tshaub muaj kev ua haujlwm zoo dua thiab ua rau lub npe ntawm cov khoom zoo dua, thiab yuav sau tau pes tsawg qhov tshuaj. No yog qhov viscosity txheeb xyuas zoo yuav pab khoom tshaub zoo dua rau lawv cov haujlwm nyob rau hauv kev siv hauv tsev tsim khoom.
1. Tswj qhov viscosity raws li kev xav tau rau txhua qhov khoom
Cov neeg tsim khoom uas tsim cov polymer, adhesive, medical thiab food yuav tsum muaj qhov viscosity zoo ib yam rau txhua qhov khoom. Yog tias viscosity yuav nce los sis, ces yuav muaj kev cuam tshuam rau qhov lubrication ntawm cov dej no, qhov paint yuav tawm los sis, thiab qhov syrup yuav tawm los sis.
Kev saib xyuas kev txaus siab ntau thiab ntau, siv lub viscometer tshwj xeeb lossis lub viscometer tshwj xeeb, muab cov lus nug txog kev ua haujlwm rau hauv qhov ua haujlwm. Yog li cas kev txaus siab tsis tau txais cov cim tshwj xeeb, cov ntaub ntawv yuav tau muab suav tom qab los ntawm kev ua haujlwm kom tsis txhob muaj kev ua haujlwm tshwj xeeb los ntawm kev ua haujlwm. Kev saib xyuas no yuav muab cov ntaub ntawv ntawm kev ua haujlwm los ntawm kev ua haujlwm, kom kev ua haujlwm yuav zoo dua thiab kom paub yuav zoo dua kom tsis txhob muaj kev ua haujlwm tsis zoo thaum ua haujlwm. Yog li cas nws yog kev xa mus rau qhov kev ua haujlwm ntawm lub roj lossis kev ua haujlwm ntawm kev kho mob, nws yog qhov tseem ceeb heev kom muaj cov cim tshwj xeeb uas yuav tsum zoo ib yam rau txhua qhov kev ua haujlwm- vim yog li cas nws yuav tsis tau txais cov cim tshwj xeeb uas tau muab sau rau hauv cov lus nug.
2. Qhia kom zoo dua thiab xaiv cov ntaub ntawv uas yuav siv
Kev qhia cov khoom siv yog qhov tseem ceeb rau qhov kev xav txog ntau yam, thiab lawv yuav muaj qhov tshwm sim uas tsis zoo ib yam. Cov khoom siv uas muaj qhov ntsuab yuav tsum muaj qhov ntsuab ntau heev kom tsis tau los ntawm lub cev, tab sis yuav tsum muaj qhov ntsuab tsis ntau heev kom tuaj yeem khiav tau. Cov lus qhia yuav tsum khiav los ntawm qhov kab laj, tab sis tsis tau los ntawm qhov kab laj, tom qab ntawd yuav tsum muaj qhov cuam ntxiv rau ntawm lub tswv. Qhov ntsuab yog qhov chaw uas pab muab cov qhov tshwm sim uas tsis zoo ib yam no los ua ke.
Kev tswj hwm ntawm kev xaiv cov khoom siv, li cas yog cov khoom siv ntawm qhov cua, cov khoom siv ua kom zoo, los yog cov khoom siv ua kom tsis muaj txhua, yuav tau ua los ntawm kev siv kev kawm kev ntsuas kev ntsuas kev ntsuas. Koj tuaj yeem kawm txhua qhov ntsuas ntawm kev ntsuas (siv cov khoom siv ntsuas kev ntsuas), los yog kawm txhua qhov ntsuas ntawm kev ntsuas (siv cov khoom siv ntsuas thiab cov khoom siv ntsuas) rau kev kawm yuav muaj dab tsi thaum cov khoom siv no nyob hauv kev sib tw, ua ntej qhov khoom siv no tau muaj ntau dua. Qhov no muaj qhov zoo tshaj plaws uas yuav muaj ntau dua kev siv khoom siv thiab txo qhov teeb meem rau kev muab cov khoom siv mus rau hauv kev sib tw. Rau cov neeg siv cov khoom siv polymer, qhov loj ntawm txhua qhov molecule yuav cuam tshuam rau qhov ntsuas ntawm cov khoom siv, yog li kev kawm yuav pab paub tias nws yuav zoo rau kev sib tw thiab kev sib tw.
3. Txo kev siv energy thiab kev siv khoom siv
Kev sib kawv thiab/los sis kawv qhov ntaub ntawv tshuaj yog qhov ua rau kev sib kawv hluav taws xob, thaum qhov ntaub ntawv tshuaj muaj qhov ntaub ntawv zoo heev. Qhov sib kawv no, yeej tshaj qhov sib kawv thiab, yog qhov sib kawv hluav taws xob heev, vim li no qhov ntaub ntawv tshuaj uas sib kawv thiab yuav tsum muaj qhov ntaub ntawv tsawg heev kom tsis sib kawv hluav taws xob, tab sis tsis txhob muaj kev pheej ywm rau qhov ntaub ntawv.
Thaum qhov ntaub ntawv uas muaj kev sib kawv tsim nyog tuaj yeem siv los test rau qhov tsawg tshaj plaws, cov ntaub ntawv uas tau txais yuav muaj kev sib kawv hluav taws xob tsawg thiab yuav muaj kev sib kawv thiab thiab lwm yam khoom sib kawv tsawg dua. Nyob rau hauv qhov chaw kho tshuaj thiab qhov chaw kho tshuaj polymer uas sib kawv tau ua tau zoo, qhov ntaub ntawv yuav tsum tau sib kawv thiab kho tau zoo. Kev kho tshuaj los sis kho tshuaj yuav tau ua tau zoo kom qhov ntaub ntawv tau zoo, thiab siv kev sib kawv hluav taws xob tsawg tshaj plaws. Cov cost no, uas tau siv tau zoo rau ib xyoo, tsis yog qhov tsawg.
4. Sib kawv rau cov kev cai thiab cov kev xav tau ntawm cov neeg siv khoom
Muaj ntau lub tshuab thiab cov kev cai uas pab txhawb rau qhov kev sib piv ntawm qhov ntsuab thiab, thiab yog tias koj cov khoom tsis tau txais cov kev cai no, nws yuav ua rau koj cov khoom tsis tau txais los yog tsis tuaj yeem xa tuaj rau cov neeg siv khoom tseem ceeb. Cov kev cai ntawd muaj ASTM D445 rau qhov tswv yim ntawm cov khoom tshuab, ISO 3105 uas pab txhawb rau qhov kev sib xyooj rau cov khoom sib xyooj ntsuab thiab cov kev cai ntau lawv uas tau muab tso rau hauv cov lus qhia rau cov khoom siv rau kev kho mob.
Kev sib xyooj qhov ntsuab thiab meej rau cov khoom uas tau muab txiav txim siab thiab muaj cov lus txhawb rau cov lus qhia yuav pab rau koj kom paub tias cov lus qhia rau cov neeg siv khoom yog meej thiab muaj kev txhawb rau cov lus qhia. Cov khoom sib xyooj qhov ntsuab thiab meej uas tau muab txiav txim siab nyob rau hauv vaj tse ntuj no yuav pab tshem cov kev sib xyooj tsis meej uas tau muab ua los ntawm neeg thiab yuav muab cov lus qhia rau cov neeg siv khoom kom paub tias cov khoom yuav ua haujlwm raws li koj tau qhia. Yog cov neeg siv khoom tau txais cov lus qhia rau cov khoom, nws yuav muaj kev paub tias cov khoom yuav ua haujlwm raws li koj tau qhia, thiab nws yuav pab rau koj kom muaj cov khoom siv tom ntej.
Cov hais txog
Kev kawm txog kev txaus siab ntawm kev sib tw ntau yam yuav pab ua kom zoo dua, ua rau cov khoom tshwj xeeb muaj kev sib xws, pab ua kom zoo dua, txo qhov loj ntawm kev tsim khoom, thiab tau txais cov kev cai ntawm tus neeg siv khoom thiab cov kev cai ntawm lub vaj. Yog li, tsuas yog khoom uas muaj qhov txaus siab los yog khoom uas muaj qhov txaus siab—tus neeg tsim khoom yuav tsum muaj kev sib tw ntau yam uas muaj kev txaus siab rau kev sib tw ntau yam, yog lawv xav tau txais qhov zoo tshaj plaws ntawm cov khoom thiab kev ua haujlwm. Hangzhou Zhongwang Technology muaj cov khoom sib tw ntau yam uas ua tau raws li kev tswj hwm—los sib tw ntau yam ntawm cov khoom uas muaj qhov txaus siab thiab lawv kuj muaj cov khoom sib tw ntau yam uas muaj qhov txaus siab rau kev sib tw ntau yam. Lawv muaj ntau yam khoom, uas koj tuaj yeem nrhiav txais ntau dua los ntawm kev hu rau lawv los nrhiav cov lus qhia tshwj xeeb uas muaj nyob rau hauv cov lus qhia tshwj xeeb.
