Sida loo habeeyo habka daabacaadda qalloocan ee khad waraaqo kartoon oo kala duwan
Noocyada caadiga ah ee warqadaha saldhigga ah ee loo isticmaalo waraaqaha dusha sare ee sanduuqa waxaa ka mid ah: xaashida looxa weelka, warqadda liner, kartoonka kraft, warqadda shaaha, warqad cad oo cad iyo warqad cad oo hal dhinac ah oo dahaarka leh. Sababo la xiriira kala duwanaanshaha qalabka waraaqaha iyo hababka waraaqaha ee nooc kasta oo warqad saldhig ah, tilmaamayaasha jireed iyo kiimikaad, sifooyinka dusha sare iyo daabacaadda waraaqaha salka ee kor ku xusan ayaa aad u kala duwan. Kuwa soo socdaa waxay ka wadahadli doonaan dhibaatooyinka ay keeneen alaabada waraaqaha ah ee kor lagu soo sheegay habka bilawga daabacaadda khadadka kartoonada.
1. Dhibaatooyinka ay keento warqadda hoose ee garaamyada hoose sanduuqa shukulaatada
Marka warqadda hoose ee garaamyada hoose loo isticmaalo sidii warqadda dusha sare ee kartoonada jiingadaha ah, calaamaduhu waxay ka soo bixi doonaan dusha sare ee kartoonada jiingadaha. Way fududahay in la keeno biibiile oo nuxurka garaafka loo baahan yahay laguma daabici karo qaybta hoose ee biibiile. Marka la eego dusha aan sinnayn ee kartoonnada jiingadaha ah ee ay sababto biibiile, saxan dabacsan oo adkaysi u leh waa in loo adeegsadaa saxan daabacaadda si looga gudbo khaladaadka daabacaadda. Cilado cad oo qaawan. Gaar ahaan kartoonnada jiingadaha ee nooca A-ka ah ee ay soo saarto warqad-grammage-yar, xoogga isku-buufinta fidsan ee kartoonada xargaha ayaa si weyn u dhaawacmi doona ka dib marka la daabaco mashiinka daabacaadda. Waxaa jira burbur weyn.dahabkasanduuqa
Haddii dusha sare ee kartoonnada jiingado ay aad u kala duwan yihiin, way sahlan tahay in ay sababto qulqulka kartoonada jiingadaha ah ee ay soo saarto khadadka kartoonada. kartoonada dunsan waxay keenaysaa daabacaad khaldan oo sax ah iyo boosas daabacaadda ka baxsan, sidaa awgeed kartoonka fidsan waa in la simo ka hor inta aan la daabicin. Haddii kartoonnada jiingadaha aan sinnayn si xoog ah loo daabaco, way fududahay in ay sababto khaladaad. Waxa kale oo ay keeni doontaa in dhumucda kartoonada jiingado ay hoos u dhacdo.
2. Dhibaatooyinka ay keento qallafsanaanta dusha kala duwan ee warqadda salka baakad-hadiyad-baakad
Marka lagu daabaco warqadda salka oo leh dusha qallafsan iyo qaab-dhismeed dabacsan, khadku wuxuu leeyahay awood sare oo qalin-daabacadu si dhakhso ah ayuu u engegaa, halka warqadda lagu daabaco oo leh siman siman oo sarreeya, fiber cufan iyo adag, xawaaraha qalajinta qalinku waa gaabis. Sidaa darteed, warqad qallafsan, qadarka codsiga khad waa in la kordhiyaa, iyo warqad siman, qadarka codsiga qalinka waa in la dhimaa. Khadka ku daabacan warqadda aan cabbirka lahayn ayaa dhaqso u engega, halka khad ku daabacan warqad cabbirkeedu uu si tartiib ah u engego, laakiin soo saaridda qaabka daabacan ayaa wanaagsan. Tusaale ahaan, nuugista khad ee xaashida cad ee dahaadhka ahi way ka hoosaysaa tan warqadaha sanduuqa iyo warqadaha shaaha, khadkuna si tartiib ah ayuu u engegaa, silcigiisuna wuu ka sarreeyaa kan warqadaha sanduuqa, warqadda liner-ka ah iyo warqadda shaaha. Sidaa darteed, xallinta dhibco yaryar oo lagu daabaco Heerku sidoo kale wuu sarreeyaa, dib-u-soo-celinta qaab-dhismeedkeeduna wuu ka fiican yahay warqadda xargaha, waraaqaha kartoonada, iyo warqadda shaaha.
3. Dhibaatooyinka ay keento kala duwanaanshiyaha nuugista warqadaha salka sanduuqa taariikhda
Sababo la xiriira kala duwanaanshiyaha warqad-sameynta alaabta ceeriin iyo cabbirka warqadda sal-dhigga, kala-duwanaanta kala duwanaanshaha, iyo dahaadhka tamarta nuugista ayaa ka duwan. Tusaale ahaan, marka si xad dhaaf ah loo daabaco warqadaha looxa cad ee dahaarka leh ee hal dhinac ah iyo kaararka kraft, xawaaraha qalajinta ee khadku waa gaabis sababtoo ah waxqabadka nuugista oo hooseeya. Si tartiib ah, sidaas darteed diiradda khadkii hore waa in la dhimaa, iyo viscosity ee khad daabacan ee xiga waa in la kordhiyaa. Daabac khadadka, jilayaasha, iyo qaababka yaryar ee midabka koowaad, oo ku daabac saxanka buuxa ee midabka ugu dambeeya, kaas oo hagaajin kara saameynta xad-dhaafka ah. Intaa waxaa dheer, daabac midabka madow ee hore iyo midabka iftiinka ee dhabarka. Waxay dabooli kartaa qaladka xad-dhaafka ah, sababtoo ah midabka mugdiga ah wuxuu leeyahay dabool adag, kaas oo ku habboon heerka daabacaadda, halka midabka iftiinka uu leeyahay dabool daciif ah, mana fududa in la ilaaliyo xitaa haddii ay jirto ifafaale baxsad ah oo ka dambeeya daabacaadda. sanduuqa taariikhda
Xaaladaha kala duwan ee cabbirka ee dusha warqadda salka ayaa sidoo kale saameyn doona nuugista khad. Warqad leh qadar yar oo cabbir ah waxay nuugtaa khad badan, iyo warqad leh qadar weyn oo cabbir ah ayaa nuugta khad yar. Sidaa darteed, farqiga u dhexeeya rullallada khadku waa in lagu hagaajiyaa iyadoo loo eegayo heerka cabbirka ee warqadda, taas oo ah, farqiga u dhexeeya rullallada khadadka waa in la yareeyaa si loo xakameeyo saxanka daabacaadda. khad ah. Waxaa la arki karaa in marka warqadda salku ay soo gasho warshadda in la tijaabiyo waxqabadka nuugista warqadda salku, isla markaana halbeeg ka mid ah waxqabadka nuugista warqadda salku la siiyo mishiinka qalabka wax lagu daabaco iyo khad qaybiyaha, si waxay bixin karaan khad oo ay hagaajin karaan qalabka. Oo marka loo eego xaaladda nuugista ee waraaqaha salka ee kala duwan, hagaaji viscosity iyo PH qiimaha khad.
