Kev tuag-txiav pov tseg tsis yog tsuas yog cov thev naus laus zis hauv kev ua cov txheej txheem ntawm cov ntawv nplaum rau tus kheej, tab sis kuj yog ib qho txuas nrog cov teeb meem tsis tu ncua, ntawm cov khib nyiab pov tseg yog ib qho tshwm sim. Thaum cov dej tawg tshwm sim, cov neeg ua haujlwm yuav tsum nres thiab rov kho cov dej ntws, uas ua rau txo qis kev ua haujlwm thiab cov khoom siv raw khoom ntau dua. Yog li dab tsi yog qhov ua rau cov khib nyiab tawg hauv kev txiav cov khoom siv tus kheej nplaum, thiab yuav ua li cas nrog nws?
Lub zog tensile ntawm raw khoom yog tsawg
Qee cov ntaub ntawv, xws li lub teeb hmoov ntawv (tseem hu ua daim iav coated ntawv), ntawv fiber ntau yog luv luv, kuj tsis yooj yim, nyob rau hauv cov txheej txheem ntawm tuag txiav pov tseg, khib nyiab ntug tensile zog yog qis dua cov khib nyiab nro ntawm cov khoom, yog li nws yog yooj yim tawg. Nyob rau hauv cov ntaub ntawv no, lub ntws nro ntawm cov cuab yeej yuav tsum tau minimized. Yog tias qhov kev tawm ntawm cov khoom siv tau raug kho kom tsawg kawg nkaus thiab tseem tsis tuaj yeem daws qhov teeb meem, tom qab ntawd nws yog ib qho tsim nyog yuav tsum tsim kom muaj qhov paug tawm dav dua nyob rau theem pib ntawm tus txheej txheem tsim los xyuas kom meej tias qhov paug tawm ntawm ntug yuav tsis nquag tawg. tuag txiav txheej txheem.
Cov txheej txheem tsim tsis tsim nyog lossis cov ntug khib nyiab ntau dhau
Tam sim no, ntau daim ntawv lo siv rau cov ntaub ntawv sib txawv ntawm kev luam ntawv ntawm kev ua lag luam tau yooj yim tearing virtual riam kab, qee cov ntawv nplaum rau tus kheej ua cov lag luam raug txwv los ntawm cov cuab yeej siv, yuav tsum muab cov riam dotted thiab rab riam ciam teb rau tib qhov chaw nres tsheb tuag; Tsis tas li ntawd, vim yog cov nqi thiab cov nqi, cov khoom pov tseg ntug tsim yog nyias nyias, feem ntau tsuas yog 1 hli dav. Txoj kev txiav tuag no muaj qhov xav tau siab heev rau cov khoom siv daim ntawv lo, thiab kev tsis saib xyuas me ntsis yuav ua rau kev puas tsuaj ntawm ntug kev puas tsuaj, yog li cuam tshuam rau kev tsim khoom.
Tus sau qhia tias tus kheej-adhesive daim ntawv lo ua lag luam, nyob rau hauv cov xwm txheej uas tso cai, sim cais cov yooj yim-rau-tear virtual riam kab los ntawm daim ntawv lo thav duab rau tuag-txiav, uas tsis tsuas yog txo qhov zaus ntawm khib nyiab ntug tawg. , tab sis kuj zoo heev txhim kho qhov tuag-txiav ceev. Cov lag luam uas tsis muaj xwm txheej tuaj yeem daws qhov teeb meem no raws li hauv qab no. (1) Kho qhov kev faib ua feem ntawm dotted riam. Feem ntau hais lus, qhov ntau ntom ntawm cov kab txiav virtual yog, qhov ntau dua nws yuav ua rau cov ntug khib nyiab. Yog li ntawd, peb tuaj yeem kho qhov feem pua ntawm cov riam dotted, xws li 2∶1 (txiav 2 hli txhua 1 hli), kom qhov tshwm sim ntawm cov ntug kev puas tsuaj yuav raug txo kom tsawg. (2) Tshem tawm ib feem ntawm cov riam virtual dhau ntawm daim ntawv lo ciam teb. Muaj ntau qhov kev tuag txiav version ntawm dotted kab riam yuav raug teem caij ntev dua, dhau ntawm daim ntawv lo, yog tias cov ntug khib nyiab thiab nqaim, ces cov dotted kab riam yuav nqaim heev pov tseg ntug thiab txiav tawm ib feem ntawm cov ntug khib nyiab, ua rau pov tseg ntug yooj yim tawg. Hauv qhov no, koj tuaj yeem siv cov ntaub ntawv shaping los ua ntaub ntawv tawm ntawm cov riam dotted uas qhia txog cov ciam teb sab nraud ntawm daim ntawv lo, uas tuaj yeem txhim kho lub zog ntawm ntug khib nyiab, kom cov ntug khib nyiab tsis yooj yim tawg.
Raw khoom tsim kua muag
Lub kua muag ntawm tus kheej-nplaum cov ntaub ntawv kuj yog ib qho yooj yim uas yuav ua rau lub tawg ntawm pov tseg ntug, uas yog kuj yooj yim mus nrhiav thiab yuav tsis tau piav nyob rau hauv daim ntawv no. Nws yuav tsum raug sau tseg tias ntug ntawm qee cov ntaub nplaum yog me me thiab tsis yooj yim rau kev nrhiav, uas yuav tsum tau ua tib zoo saib xyuas. Nyob rau hauv rooj plaub ntawm cov teeb meem zoo li no, cov khoom tsis zoo tuaj yeem raug tshem tawm thiab txiav tuag.
Tus nqi ntawm cov nplaum txheej hauv cov khoom siv nplaum muaj qhov cuam tshuam zoo rau kev tuag txiav kev ua haujlwm ntawm cov khoom nplaum. Feem ntau, ntawm cov cuab yeej txiav tuag, kev tuag-txiav cov ntaub ntawv uas tus kheej-nplaum tsis yog tam sim ntawd tawm, tab sis kom txuas ntxiv mus rau qhov kev ncua deb rau pem hauv ntej, mus rau qhov chaw nres tsheb pov tseg ua ntej pib tawm. Yog hais tias cov nplaum txheej yog tuab heev, nyob rau hauv cov txheej txheem kev sib kis ntawm qhov chaw txiav tuag mus rau qhov chaw nres tsheb pov tseg, cov nplaum yuav rov qab, ua rau cov nplaum nplaum uas tau raug txiav thiab lo ua ke, ua rau cov khib nyiab pov tseg thaum rub tawm. nce vim adhesion thiab tawg.
Feem ntau hais lus, txheej txheej ntawm cov dej-soluble acrylic nplaum yuav tsum nyob nruab nrab ntawm 18 ~ 22g / m2, thiab cov txheej txheem kub yaj nplaum yuav tsum nyob nruab nrab ntawm 15 ~ 18g / m2, ntau dua li qhov ntau ntawm cov khoom siv nws tus kheej, qhov tshwm sim ntawm khib nyiab ntug tawg yuav loj heev. Qee cov adhesives txawm tias cov txheej txheej tsis loj, tab sis vim nws cov khoom muaj zog, nws yooj yim ua rau khib nyiab adhesion. Nyob rau hauv rooj plaub ntawm cov teeb meem zoo li no, koj tuaj yeem soj ntsuam thawj zaug seb puas muaj qhov tshwm sim loj ntawm qhov khib nyiab thiab daim ntawv lo. Yog tias qhov tshwm sim ntawm kev kos duab loj heev, nws tau hais tias gelatine nplaum txheej yog qhov loj lossis cov dej muaj zog. Nws tuaj yeem daws tau los ntawm txheej txheej qee cov roj silicon ntawm cov riam txiav tuag, lossis los ntawm kev ua kom sov lub pas nrig hluav taws xob. Silicone additives tuaj yeem ua rau qeeb qeeb ntawm qhov rov qab ntawm cov nplaum, thiab cua sov cov khoom siv nplaum tuaj yeem ua rau cov nplaum nplaum sai sai, thiaj li txo cov qib ntawm cov hlau kos duab.
Tuag txiav cov cuab yeej tsis xws luag
Tuag txiav riam tsis xws luag kuj yog ib qho yooj yim ua rau khib nyiab ntug tawg, piv txwv li, qhov sib txawv me me ntawm ntug ntawm riam yuav ua rau cov ntaub nplaum nplaum tsis tuaj yeem txiav tawm tag nrho, qhov tsis raug txiav yog qhov tseem ceeb piv nrog rau lwm qhov. , nws yog ib qho yooj yim rau tawg. Qhov tshwm sim no kuj yooj yim rau kev txiav txim vim tias qhov chaw ntawm qhov tawg yog tsau. ntsib cov xwm txheej zoo li no yuav tsum tau kho cov riam puas tuag ua ntej, thiab tom qab ntawd siv rau kev txiav tuag.
Lwm cov lus nug thiab cov hau kev
Ntxiv nrog rau kev hloov cov ntaub ntawv raw, muaj ntau txoj hauv kev los daws qhov teeb meem los ntawm kev hloov cov txheej txheem Angle, xws li oblique paug, pre-stripping, ncaj kab, cua sov, lub tshuab nqus tsev vacuum, dislocation method, thiab lwm yam 1. Oblique khib nyiab pov tseg hauv tuag txiav tshwj xeeb-zoo li daim ntawv lo, tuag txiav modulus ntau dhau, vim hais tias cov khib nyiab khib nyiab tsis zoo ib yam, nws yog ib qho yooj yim mus rau ib sab ntawm qhov tshwm sim ntawm tsis ua hauj lwm los yog tawg, ces tuaj yeem kho lub kaum sab xis ntawm cov khib nyiab phau ntawv yob los daws cov teeb meem ntawm khib nyiab tawg. 2. Pre-stripping Hauv kev txiav tuag ntawm cov ntawv tshwj xeeb thiab cov ntawv loj, kev kho ua ntej stripping tuaj yeem ua tiav ua ntej kev txiav tuag kom txo tau lub zog stripping ntawm cov khoom thaum pov tseg. Tom qab kev kho mob ua ntej ntawm cov khoom siv, lub tev tawm tuaj yeem raug txo los ntawm 30% ~ 50%, qhov tshwj xeeb peeling quab yuam txo tus nqi nyob ntawm cov khoom. Nws yog ib qho tsim nyog sau cia tias cov nyhuv ntawm online pre-stripping yog zoo dua. 3. Txoj kab ncaj nraim Rau cov khib nyiab pov tseg uas tshwm sim los ntawm qhov hnyav thiab loj tuag txiav modulus, txoj kab ncaj tuaj yeem siv los txo qhov kev sib cuag nrog cov ntawv pub mis rau cov menyuam ua ntej pov tseg, tiv thaiv daim ntawv lo ntawm cov khib nyiab. vim lub overflow ntawm kua nplaum vim nro extrusion. 4. Thaum lub tshuab nqus tsev nqus cov khib nyiab tuag txiav, ib feem ntawm daim ntawv lo yog qhov loj heev, thiab lub tshuab nqus tsev nqus yuav siv tau los nqus cov ntug ntawm cov khib nyiab pov tseg, tab sis yuav tsum tau them nyiaj rau qhov ruaj khov ntawm qhov nqus, qhov loj ntawm lub tshuab nqus tsev vacuum. suction yuav tsum tau ua ke nrog cov thickness ntawm cov khoom, qhov loj ntawm cov ntug khib nyiab, thiab qhov ceev ntawm lub tshuab. Txoj kev no tuaj yeem ua tiav cov khoom pov tseg tsis nres. 5. Dislocation ntawv cov ntaub ntawv tuag txiav module yog ntau dua, qhov dav ntawm txoj kab uas hla transverse me me, txoj kab uas hla transverse yog yooj yim tawg los yog kab thaum tshem tawm cov khib nyiab, ua cov riam kem thiab kem staggered, tuaj yeem buffer qhov nro thaum transverse txoj kab uas hla khib nyiab. , tab sis kuj tuaj yeem txhim kho lub voj voog kev pabcuam ntawm riam tuag.
