Ku dar dahaarka budada oo ku buufi dahaarka budada

1. Fikrado kala duwan

1) Ku buufi daahan budada ah:

Daahan budada ah waa habka daaweynta dusha sare ee ku lug leh ku buufinta budada alaabta. Budada badanaa waxa loola jeedaa daahan budada heerkulbeegga. Dusha sare ee alaabta budada-dahaarka leh way ka adag tahay oo ka jilicsan yihiin kuwa alaabta lagu dhuuqo. Koronto-dhaliyeyaasha ayaa loo isticmaalaa in lagu dallaco budada, taas oo markaa soo jiidata dusha sare ee saxanka birta. Ka dib marka la dubayo at 180-220 ℃, budada dhalaalaysaa oo ku dheggan birta. Alaabooyinka budada ah ayaa badanaa loo isticmaalaa isticmaalka gudaha, iyo filimka rinjigu wuxuu leeyahay dabaq ama matte ama saameyn farshaxan.

2) Dahaarka budada ah:

Daahan budada dufanku waxay ku lug leedahay kuleyliyaha birta oo si siman ugu dahaadhi budo caag ah si ay u sameeyaan filim caag ah, ama kuleylinta iyo dhex galinta birta xal daahan si ay u qaboojiso oo u sameeyaan filim caag ah oogada birta. Budada inta badan waxaa loola jeedaa dahaarka budada thermoplastic. Dahaarka dhexda waxaa loo qaybin karaa dahaarka dhuubka kulul iyo daahan qabow, depeiyadoo la eegayo in kululaynta loo baahan yahay, iyo dahaarka dhuubka dareeraha ah iyo daahan budada ah, depeoo ku saabsan alaabta ceeriin ee loo isticmaalo.

2. Hababka processing kala duwan

1) Waxaa jira noocyo kala duwan oo daahan budada buufiyo, sida budada akril, budada polyester, iyo epoxy polyester budada. Daahan budada buufiyo waxay leedahay tayada badeecada iyo culeyska sare ee daahan budada ah, laakiin dusha alaabadu waa u fiican oo siman labada habba.

2) Daahan dahaarka ah ayaa ka raqiisan daahan budada buufinta sababtoo ah qiimaha budada dahaarka ayaa ka hooseeya tan birta. Daahan budada dip waxay leedahay faa'iidooyinka ka hortagga daxalka iyo ka-hortagga miridhku, caabbinta acid iyo alkali, caabbinta qoyaanka, dahaarka, taabasho wanaagsan, ilaalinta deegaanka, iyo nolosha adeegga dheer. Dhumucdiisuna waxay daahan tahay guud ahaan ka dhumuc weyn yahay daahan budada buufiyo, oo dhumucdiisuna waxay ka badan tahay 400 microns marka la barbar dhigo 50-200 microns ee daahan budada buufiyo.

1) budada dahaarka:

①Daahan budada madaniga ah: inta badan waxaa loo isticmaalaa dahaadhida maro-sharafyada dharka, baaskiilada, dambiisha, weelka jikada, iwm. Waxay leeyihiin socodka wanaagsan, dhalaalaya, iyo cimri dherer.

②Engineering budada daahan: loo isticmaalo in lagu dahaadho jidadka weyn iyo jidadka tareenada, injineernimada dawladda hoose, qalab iyo mitir, dukaamada supermarket-ka, khaanadaha talaajadaha, fiilooyinka, iyo alaabta kala duwan, iwm. Waxay leeyihiin adkeysi xoog leh iyo iska caabin daxalka.

2) Mabda'a daahan:

Daahan dahaarka ah waa hab kuleyl kaas oo ku lug leh kulaylka birta ka hor, ku dhex rida xal daahan, iyo daawaynta. Inta lagu jiro quusinta, birta kuleylku waxay ku dheggan tahay walxaha ku xeeran. Sida uu u kululaado birta, waa sii dheeraana wakhtiga wax-ku-daaqista, iyo dhumucda dahaarka. Heerkulka iyo qaabka xalka dahaarka ayaa go'aaminaya qadarka balaastiigga ee ku dheggan birta. Dahaarka Dip wuxuu abuuri karaa qaabab yaab leh. Habka dhabta ah wuxuu ku lug leeyahay daahan budada ah oo lagu daro weelka hoose ee daloolka ah (taangiga socodka), kaas oo ka dibna ay kacdo hawo cadaadis leh oo lagu daaweeyo afuufiye si loo gaaro "xaalad dareere ah", sameynta budo ganaax ah oo si siman loo qaybiyay.

3. Wax la mid ah 

Labaduba waa hababka daaweynta dusha sare. Midabada labada hab waxay noqon karaan huruud, casaan, caddaan, buluug, cagaar, iyo madow.
