Dahaarka biyaha ku salaysan vs. dahaarka dareeraha ku salaysan

Dahaarradu waxay inta badan magacooda ka qaataan binder-ka, ama resin, kaas oo laga sameeyay. Soobaxyada, alkyds iyo urethane waa dhammaan tusaalooyinka xabagta oo bixisa dahaarka magacooda. Laakiin kuwani maaha qaybaha kaliya ee ka samaysan dahaarka. Marka lagu daro waxyaabaha lagu daro, kuwaas oo amaahin kara dahaarka sifooyinka waxqabadka qaarkood, iyo pigments-ka bixiya midabka, dahaarka sidoo kale waxaa ku jira walxo ku milma dhammaan dareeraha si sahlan loo isticmaalo.

Wakiilka dareeraha ah wuxuu caadi ahaan u qaataa qaabka biyaha ama wax kale oo kiimiko ah. Sidaa darteed ereyada "biyo-ku-saleysan" iyo "ku-saleysan millatariga". Nooca badeecada ku habboon shaqada waxay ku xirnaan doontaa duruufaha. Guud ahaan, mid ka mid ah kama roona kan kale, laakiin waxay sameeyaan si ka duwan xaaladaha kala duwan. Sida ugu fiican, labada ikhtiyaarba waxay u jiri doonaan dhinac-dhinac ee arsenal-ka xirfadleyda dahaarka.

DAHABKA BIYAHA KU SAABSAN

Rinjiyeynta biyaha ku salaysan waxay ka kooban yihiin boqolkiiba 80 rinjiga guryaha maanta la iibiyo sida uu qabo machadka tayada rinjiga, oo ah hay'ad latalinta rinjiga iyo tijaabinta. Shaki kuma jiro in tani ay qayb weyn ka tahay mid ka mid ah soo jiidashada ugu weyn ee alaabta biyaha ku salaysan, haddii ay tahay rinjiga guriga gudaha ama dahaarka ilaalinta culus: ur yar.

Markaad ka shaqaynayso meelo xaddidan ama hawo liidato, uumiga dareerayaasha waxay dhib ku noqon karaan shaqaalaha ama xitaa waxay soo bandhigaan khatar caafimaadkooda. Sababtan awgeed, mashruucyo badan sida kuwa ku lug leh haamaha kaydinta shidaalka iyo baabuurta taangiyada tareenada ayaa isticmaala dahaarka biyaha ku salaysan. Kuwani waxay sidoo kale yareeyaan isku-duubnaanta alaabta gubanaysa ee ku ururta meel xaddidan. Taas macnaheedu maaha, si kastaba ha ahaatee, isticmaalka dahaarka biyaha ku salaysan ayaa diidaya baahida loo qaboOSHA waxay ansixisay tallaabooyinka badbaadada meel xaddidan.

U hoggaansanaanta deegaanka ayaa ah sabab kale oo caan ah oo lagu dooranayo isticmaalka daahan biyaha ku salaysan. Qalabyo badan ayaa u baxa waxa loo yaqaan xeryahooda organic kacsan, ama VOCs. Dawladaha qaranka, gobolka iyo dawladaha hoose ayaa inta badan nidaamiya VOC-yada iyaga oo xaddidaya inta ganacsi ee loo oggol yahay inay sii daayaan muddo cayiman. TheEPA ayaa dejisa xeerar qaranloogu talagalay VOC-yada, laakiin gobollada qaarkood waxay sii xoojiyeen xannibaadaha, taas oo u baahan dadaallo wadajir ah oo lagu xaddidayo qiiqooda.

Dahaarka biyaha ku salaysan qasab kuma aha inay ku jiraan wax dareere eber ah, in kastoo. Qaar badan ayaa ka kooban waxa loo yaqaan co-solvents, dareerayaasha ku jira xaddi hoose oo loogu talagalay in lagu riixo inta ka hartay biyaha daaha marka ay engegaan. Laakin mar haddii daaha-ku-saleysan biyaha ay leeyihiin ama maya, ama dareerayaal aad u yar, waa hab wanaagsan oo lagu dhimo wax soo saarka VOC ee ganacsiga. Shirkadaha qaarkood, tani waxay la macno tahay inay kharash yar ku bixiyaan la-talinta u hoggaansanaanta deegaanka. Ama ka ilaali inay bixiyaan ganaaxyo waaweyn oo ka badan kootada VOC.

DABADAHA KU SALAYSAN XAL

Rinjiyeynta millatariga ku salaysan waxay ka samaysan yihiin walxo dareere ah oo loogu talagalay inay ku soo baxaan fal-celin kiimikaad oo leh ogsijiin. Caadi ahaan, dhaqdhaqaaqa hawada ee ku wareegsan dahaarka ku salaysan dareeraha ayaa kaa caawin doona inaad dedejiso falcelinta, yaraynta wakhtiyada qalajinta.

Dahaarkani waxay leeyihiin hal faa'iido weyn marka loo eego dahaarka biyaha ku salaysan. Waxay u nugul yihiin xaaladaha deegaanka sida heerkulka iyo qoyaanka inta lagu jiro marxaladda daaweynta. Qoyaanka ayaa dhab ahaantii ka hortagi kara biyaha ku jira dahaarka biyaha inay soo baxaan, taasoo ka dhigaysa kuwo aan waxba ka qaban karin cimilada qaarkood.

Dahaarka biyaha ku salaysan ayaa sidoo kale caqabad ku ah marxaladda diyaarinta dusha sare ee mashruuca daahan. Biyaha, iyada oo beddelka rajooyinka leh ee dareerayaasha xaaladaha qaarkood, sidoo kale waa qayb muhiim ah oo ka mid ah geeddi-socodka daxalka, sababta oo ah dhammaan sababta warshadaha dahaarka warshadaha ee meesha ugu horeysa. Haddii biyuhu ay la xiriiraan substrate-ka ka hor inta aan daahan la marin, waxaa laga yaabaa in miridhku uu bilaabo inuu dhaco. Si loo hubiyo in tani aysan ahayn kiiska, daboolka biyaha ku salaysan waa in la sameeyaa si dhammaan biyaha laga soo saaro filimka dusha sare ka hor intaysan dhicin daxalka. Tani ma aha tixgalin la leh dahaarka dareeraha ku salaysan.

Markaa, marka la soo koobo, in kasta oo dahaadhka biyaha ku salaysani ay u noqon karaan door wanaagsan oo loogu talagalay shaqooyinka ku lug leh meelaha bannaan iyo isticmaalka dahaarka joogtada ah, kama maqan yihiin dhibcahooda daciifka ah. Shaqooyinka furan, xaaladaha qoyan, sida kuwa inta badan laga helo kaabayaasha mashaariicda dib-u-celinta, ayaa wali ka faa'iideysan kara dahaarka saxda ah.
