Inkomoko y'urupapuro rwa Kraft

Kraft Paperthe ijambo rijyanye n '"imbaraga" mu kidage ni "cowwhede".

Ku ikubitiro, ibikoresho fatizo byimpapuro byari imyenda n'amayeri bikoreshwa. Nyuma, hamwe no guhanga igikoni, uburyo bwo gukurura imashini bwafashwe, kandi ibikoresho fatizo byatunganijwe muburyo bwa fibrous binyuze muri crusher. Mu 1750, Hernda Bica wo mu Buholandi yahimbye imashini y'impapuro, kandi umusaruro ukomeye watangiye. Icyifuzo cyibikoresho by'ibishushanyo fatizo birenze urugero.
Kubwibyo, mu ntangiriro z'ikinyejana cya 19, abantu batangiye gukora ubushakashatsi no guteza imbere ubundi buryo bw'impapuro mbisi. Mu 1845, Keira yahimbye ubutaka. Ubu bwoko bwa pulp bukozwe mu biti kandi bijanjagurwa mu fibre binyuze muri hydraulic cyangwa igitutu. Nyamara, ibiti byimbaho ​​bigumana ibice hafi ya byose byibikoresho, hamwe na fibre ngufi kandi idahangayitse, isuku yo hasi, imbaraga zintege nke, noroshye umuhondo nyuma yububiko burebure. Ariko, ubu bwoko bwa shop ifite igipimo cyinshi nigiciro gito. Gusya ibiti bikunze gukoreshwa mugukora amakuru nikarito.

Mu 1857, Hutton yahimbye shimi. Ubu bwoko bwa pulp burashobora kugabanywamo bulp, sulfate pulp, na caustic soda pulp, bitewe numukozi wa jeweringa wakoreshejwe. Uburyo bwa Caustic Soda buvumbuwe na Hardton bikubiyemo ibikoresho bibisi mu gisubizo cya sodium hydroxide ku bushyuhe no mu gitutu. Ubu buryo bukunze gukoreshwa mubiti byagutse kandi bituje nkibikoresho byo gutera.
Mu 1866, Chiruman yavumbuye sulfite lulfe, yakozwe mu kongeramo ibikoresho fatizo ku gisubizo kirenze urugero kirimo sulftite irenze urugero no kubiteka mu bushyuhe no guteka mu gihe cyo gukuraho umwanda nko gutiza mu bice by'ibihingwa. Guhumeka kw'ibintu n'ibiti bivanze hamwe birashobora gukoreshwa nkibikoresho fatizo byamakuru, mugihe igikumpeke cyanduye kibereye kubyara impapuro zishira imbere nimpapuro.
Mu 1883, Dartu yahimbye pulfate ya sulfate, ikoresha imvange ya sodium hydroxide na sodium sulfide ya sodium kumuvuduko mwinshi hamwe nubushyuhe bwinshi. Kubera imbaraga za fibre nyinshi za panp zikorwa nubu buryo, yitwa "compade compa". Kraft Pulp iragoye kuri Byakunzwe kubera Ligin ya Brown igisibo, ariko ifite imbaraga nyinshi, bityo impapuro zabigenewe zirakwiriye cyane kurupapuro rwo gupakira. Ihuriro ryakozwe naryo rishobora kandi kongerwa kurundi rupapuro kugirango ushyireho impapuro, ariko zikoreshwa cyane cyane impapuro za Kraft nimpapuro. Muri rusange, kuva hagaragaye kuvugurura imiti nka sulfite pulp na sulfate pulp, impapuro zahindutse kuva kubintu byiza kuri ibicuruzwa bihendutse.
Mu 1907, Uburayi bwateje imbere pulp na Hemp Bivanze Pulp. Muri uwo mwaka, Amerika yashyizeho uruganda rwa mbere rwa Kraft. Amashyaka azwi kuba washinze imifuka "ya Kraft". Yabanje gukoresha impapuro zo gupakira umunyu nyuma yo kubona ipatanti ya "bates pulp".
Mu 1918, Amerika n'Ubudage byatangiye gukora imikoreshereze y'impapuro za Kraft. Igitekerezo cya "guhuza amakuru yimpapuro zipakira" kandi icyifuzo cyacyo cyatangiye kugaragara muri kiriya gihe.
Isosiyete y'impapuro za Santo Rekis muri Amerika yinjiye mu isoko ry'Uburayi nkoresheje imashini idoda tekinoloji yo kudoda tekinoroji, yaje kugezwa mu Buyapani mu 1927.
