Ubuninzi bephepha le-Whatman kunye nezinye iintlobo zamaphepha

Ubuninzi be-Whatman okanye iphepha lokushicilela lubaluleke kakhulu. Lo mqathango ubeka ubungakanani bawo bokusetyenziswa, uprinte umgangatho kunye nokuzinza komshicileli. Ziyintoni ubuninzi beentlobo ezahlukeneyo zamaphepha, kunye nendlela yokukhetha okulungileyo kwimihlobo ethile yamaphepha?

Ubungakanani kunye nobukhulu abufani

Ukuthetha ngokuxininisa, ezininzi zithetha ubukhulu bephepha, kodwa oku kuyiphutha. Iphepha eliphangaleleyo lephepha elibonakalayo libonakala likhulu kunomnye, ngelixa izibonakaliso zentsholongwane yazo zingafana.

Enyanisweni, iphepha eliqinileyo liyancipha kwaye likhupha, liyakwazi ukugqoka kwaye linomsebenzi omfutshane wokunceda. Ngoxa i-thin one enezinga eliphezulu lixineke kwaye liza kuhlala ixesha elide. Yaye i inki isetyenziswe ngokulinganayo, eyona nto iphambili ekunyatheliseni okuchanekileyo kumgangatho. Ngoko ke, iphepha elincinci alinakuhlala libi.

Luhlobo luni lwamaphepha asetyenziswayo?

Kwimimandla eyahlukileyo, iphepha leentlukwano ezisetyenziswayo lisetyenzisiweyo. Umzekelo, ukushicilela kudinga iimpawu ukusuka kwi-60 ukuya ku-300 g / m ² . Ngaphantsi kancinane lesi sibalo se-newsprint - kuphela 45-60 g / m ² . Ukubhala iphepha okanye iphepha le-watercolor yeencwadi kunye namakhadi-shishini - zonke ezi ziintlobo ezithile kunye noxinzelelo oluthile, imigaqo elawulwa ngokuthe ngqo. I-Whatman inezibonakaliso ezicacileyo, ezijoliswe kwi-GOST.

Ukuthetha malunga nephepha, ku funeka kuqatshelwe ukuba le yile fomati enkulu kakhulu esetyenziswe kwinkalo yoyilo kunye nobugcisa. Unandipha ukuthandwa kakhulu phakathi kwabantu abanezakhono ezahlukeneyo.

Ukunyaniseka nokupasa komgangatho

Ubuninzi bephepha kunye neenkcukacha zedivayisi yokuprinta zihambelane kakhulu. Kwimiyalelo yomshicileli ngamnye, umenzi udla ngokucacileyo ifomathi kunye nencomo. Ukumakisha i-A4, 64-163 g / m ² , umzekelo, uthetha ukuba lolu hlobo lwephepha lufanelekile kwesi sixhobo. I-Whatman enobudlelwane ngaphezu kokuvumelekileyo ayiyi kusebenza-inokuyonakalisa indlela kwaye ifake umshicileli ngaphandle kokusebenza.

Ngokuqhelekileyo, iiprinta zeofisi eziqhelekileyo kunye neepopi zisebenzisa ubukhulu bephepha A3 kunye ne-A4, ngeqondo eliphakathi kwe-80 g / m ² . Zizo zikhokelo ezikhokela abavelisi, ukuvelisa iphepha lokushicilela. Ngamnye wabo uvelisa uphawu lwakhe, enesiqinisekiso sokuprinta kwekhwalithi ephakamileyo kwiphepha lelophawu. Ngokomzekelo, iimveliso zelwimi lwasekhaya "I-Snow Maiden" zithandwa kakhulu kwiiofisi zethu.

Ubukhulu bephepha kunye neGOST

Ukuba ukuxinwa kwaziwa, ngoko ubunzima bephepha eliphinda lilula ukuzimisela. Umzekelo, iphepha le-A4 elinamanani kwi-package ye-80 g / m ² iya kubala ubuncinane malunga no-5 amagremu. Kwimimiselo eqhelekileyo yamaphepha ama-500 amaphepha, ngoko ubunzima bepakethi kuya kuba malunga neekhilogram ezi-2.5. Ukuba ubunzima obugqithiseleyo bungaphezulu kwesi sibalo, mhlawumbi, izimo zokugcina azizange zigcinwe, kwaye inqanaba lokunyamezela lephepha liphezulu kuneliqhelekileyo.

Iphepha lokuprinta iofisi, iincwadi kunye neetheyibhile, kunye nobunzima be-160 g / m² ziza kuba neenalathisi ukusuka kwi-800 ukuya kwi-900 kg nganye nganye yamithayubhi nganye. Ngaphantsi kwama-160 - ukususela kwi-750 ukuya ku-850 kg / m³ Akukho kuphela ukukhupha iphepha eliqhelekileyo. Ubuninzi be-GOST bubeka kuyo kwinqanaba lika-850-950 kg / m³. Iphephandaba linesixinanci esiphantsi, liphepha elincinci. Ixesha "lobomi" balo liintsuku ezimbalwa, emva koko umenzi akakwazi ukuqinisekisa ukuqina: iphepha elinjalo liqala ukunyuka kwaye litshintshe.

Kuxhomekeke kwimisebenzi yokushicilela, ubuninzi, kunye nobunzima nobunzima bephepha, kunokutshintsha. Kuze kube yimini, kukho imigangatho eyahlukileyo, kwaye ukufumana yonke imigaqo nganye ayinzima.

I-Whatman iyiphepha leprayimenti

Ubuninzi bephepha liphezulu kunezinye iindidi zamaphepha, ngoko ke kuthathwa njengemveliso engaphezulu. Iifomathi eziqhelekileyo zininzi: ukusuka ku-A1 ukuya kwi-A4 (ungaphinda ufumane iphepha le-Whatman yefom ye-A5), elowo lunobunzima balo - kwi-range ukuya kwi-120 ukuya kwi-200 g / m². Kwaye kukho iphepha le-A0 kunye nemigqaliselo emangalisayo yeqabunga 841х1189 yabona eli phepha malunga nobukhulu liya kuba ngaphezulu, kunamanye amafomathi athathwe ndawonye.

Ukongezelela kwezo zikhombisi ezifana nobukhulu nokuxininisa kwiphepha, ukubaluleka kwe-pulp kubalulekile, okuphucula umgangatho wokushicilela. Kwaye ukuphakama okuphezulu kwiphepha kukuvumela ukuba uprinte okanye udwebe kuwo kumabini omabini.

Indlela yokufumanisa ukuba lo mgangatho wangempela uWeman? Okokuqala kukho konke ukubonakala: iphepha limhlophe, likhulu kwaye lilule. Ukuba ungathandabuzeki, lahla amanzi amancinci kwiphepha. Ukususela kwiphepha lakhe lokudweba akufanele likhubazeke. Oku akusetshenziswanga ukudweba kuphela, kodwa kunye nokudweba - iinki, inkenki okanye ipensela. Nangona kule njongo, abaculi beengcali bavame ukuthenga iphepha elikhethekileyo le-watercolor, elinomlinganiselo ophezulu kunye nokuxutywa kwamanzi.

Uphi na ukuthenga phi i-Whatman?

Ngoko, uyazi, imiphi imisebenzi oyifunayo eli phepha, uyazi ukuba ubuninzi bephepha kufuneka ukuba yintoni, kodwa ukuyithenga kuphi? Ngokuqhelekileyo, kwivenkile yokubhala okanye i-bookshop. I-Whatman ithengiswa ngexabiso elithengiweyo- kwiphepha le- A1 ifomathi uya kufuneka uyihlawule ngaphezu kwe-ruble engama-20. Iifomati ezincinci ziza kuhlawula ixabiso.
