Ibipimo by'ubucucike bw'umurongo, nka Lonnmeter tuning fork density meter, bitanga igipimo nyacyo cy'imiterere ya nitrocellulose lacquer irimo solvents nyinshi zishyuha kugira ngo zikoreshwe mu nganda. Gukurikirana ubucucike bw'igihe nyacyo bigumana ikigereranyo nyacyo cy'ubucucike hagati ya solvent na resin, bigira ingaruka ku buryo butaziguye ku bwiza bw'ubucucike bw'ibara, ubwiza bwa filime, no ku buryo ikoreshwa rihoraho. Ku bijyanye n'uburyo bwo gukwirakwiza ibara mu gutwikira, kugumana ihindagurika ry'ubucucike mu gipfundikizo kiri hagati ya ± 0.5% bituma uduce dutose neza kandi bikarinda ihindagurika ry'ubwoko bwose.
Gusubiza vuba bigabanya ibyago byo kwangirika kw'ibinyabutabire bitewe n'uko ibintu bidahuye cyangwa ibara ry'ibinyabutabire rishobora kwiyongera. Ibinyabutabire bishyuha cyane byo gutunganya polymer bisaba kugenzura ubucucike bwa hafi kugira ngo hirindwe ko ibintu bitagenda neza mu gihe cy'umwuka no gukora firime idahuye. Amakuru yihuse atuma habaho gukosora vuba—kugabanya gusubiramo, kunoza umusaruro, no kwemeza ko buri gice cyujuje ibisabwa mu gukurura no kunyuramo kw'ibinyabutabire.
Lacquer ya Nitrocellulose

Intangiriro
Lacquer ya nitrocellulose ishingiye ku kugenzura neza ubucucike kugira ngo igere ku bwiza buhanitse kandi buhamye bwo gusiga. Ibipimo by'ubucucike bw'imirongo, nka Lonnmeter tuning fork density meter, bikurikirana neza ibipimo by'amazi mu gihe cyo kuvanga. Ibipimo nyabyo bigumana ikigereranyo cyiza cya solvent-to-resin, cyane cyane hamwe n'ibinyabutabire byinshi byo guteka bikoreshwa mu nganda. Uburyo bwiza bwo gukwirakwiza ibara ry'umuhondo - ibyuma bisya, ibinyabutabire byihuta, ikoranabuhanga rya ultrasonic - bisaba guhitamo neza ibinyabutabire kugira ngo ibara ritagorana. Guhindura ubucucike bw'imirongo mu buryo nyabwo bitanga isura imwe, imiterere myiza ya filime, no kunoza ubucucike bwa filime ku bikoresho by'imodoka n'ibikoresho. Ubushakashatsi mu nganda bwerekana filime nto za nitrocellulose lacquer, zakozwe mu buryo bw'ibice byinshi, zitanga ubucucike bwiza kandi bugaragara. Gupima ubucucike bw'imirongo bituma habaho gukosora ako kanya, kugabanya ihinduka ry'itsinda no gushyigikira umusaruro munini.
Incamake y'Inzira Igenda
Imashini zigenzura zivanga nitrocellulose n'ibinyabutabire bifite ubushyuhe bwinshi bikoreshwa mu nganda, nka butyl glycol na dibutyl phthalate. Inyongeramusaruro n'ibinyabutabire bishyirwamo kugira ngo byongere ubwiza n'ubukonje. Igipimo cy'ibinyabutabire ni ingenzi cyane; ibinyabutabire nyabyo bishonga nitrocellulose mu gihe ibinyabutabire n'ibitari ibinyabutabire bitunganya ubushyuhe n'irangira ry'ubuso.
Uburyo bwo gukwirakwiza irangi no kurimbika burimo ibikoresho bikwirakwiza irangi byihuta cyane, ibikoresho bitunganya amasaro, na ultrasound cavitation. Ibi bituma irangi ringana, bikarinda guhurirana no gutuma firime idahindagurika. Gukwirakwiza irangi neza bituma firime igaragara neza kandi igakwirakwira neza.
Ubucucike n'ubucucike bigenzurwa neza no guhindura ingano y'ibinyabutabire. Ibipimo by'ubucucike byo gupima amazi, harimo na metero ya Lonnmeter tuning fork density meter, bitanga agaciro k'igihe nyacyo mu gihe cyo kuvanga, bikerekana ko intego inyuramo kandi ko urumuri rugaragara.
Imiterere ya firime ipimwa mu murongo kugira ngo harebwe niba irabagirana, ifatana, kandi itwikiriye, hakoreshejwe ibikoresho byo gupima biri mu mirongo y'imikorere. Uburyo bwa nyuma bwa nitrocellulose lacquer n'imikoreshereze yabwo bibungabungwa binyuze mu kohereza mu miyoboro ifite ibipimo by'ubucucike bw'umurongo kugira ngo hakorwe irangi rinini ry'urumuri hamwe na nitrocellulose lacquer. Ibi bitanga imiterere myiza kuva ku itsinda rimwe kugeza ku rindi.

Imbogamizi mu gupima ubucucike bw'umubiri
Imiti ishyushya cyane igabanya ubushyuhe, bigatuma ibimenyetso by’ubucucike bw’amazi bihindagurika cyane mu gihe cyo gukora lacquer ya nitrocellulose. Imiti ikoreshwa mu nganda ikoresha imiti ishyushya ifite ubushyuhe buri hejuru ya 140°C (urugero: xylene, butyl acetate) igaragaza ihindagurika rya 6% ku isaha bitewe n’impinduka mu kirere, ubushyuhe, n’umuvuduko w’amazi.
Uburyo bwo gukwirakwiza ibara nk'ubucukuzi bw'amasaro n'ubucukuzi bwa ultrasonic buhura n'uburyo bwo gukusanya ibintu mu buryo buciriritse; uburyo bwo gushyiramo ibintu mu buryo butari bumwe buhindura ubwiza bw'ubucukuzi, bigatuma imiterere ya firime ihinduka hagati ya 3–15%. Iyo hatabayeho kugenzura mu buryo bufatika, guhagarara kw'ibara no kwirema kw'amatsinda ntibigaragara, bikagira ingaruka ku buryo butaziguye ku gipimo cy'ubucukuzi bwinshi.
Mu gihe cyo kwagura, kubungabunga ikwirakwizwa ry’amazi mu buryo bumwe biragoye iyo hatabayeho ibipimo by’amazi biri ku murongo. Ibikoresho bivanga amazi byongera umusaruro ariko byongera ibyago byo kutagera ku rugero rumwe iyo guhitamo ibinyabutabire cyangwa ingufu zo guhindagurika bihindutse. Ibipimo by’ubucucike bw’amazi bisanzwe muri laboratwari—pycnometry cyangwa hydrostatic wearing—ntibishobora guhuza n’ihindagurika ry’ubucucike bw’amazi mu buryo bw’igihe nyacyo, cyane cyane mu migendekere y’amazi.
Guhagarika ibikorwa, guhumanya ibikoresho, no kwibumbira ku buso bw'ibikoresho byo mu bwoko bwa sensor bituma amakuru adahinduka neza. Gukosora mu buryo bwikora ni ngombwa; gusoma intoki bitinza igisubizo kugeza ku minota 90 kuri buri gice, bigatuma habaho ikoreshwa rya lacquer ya nitrocellulose idasobanutse neza.
Ibyiza byo guhuza ibipimo by'ubucucike bw'umuvuduko / ibipimo by'ubucucike bw'umuvuduko
Ibipimo by’ubucucike bw’imbere mu buryo bw’igihe nyacyo n’ibipimo by’ubucucike bitanga uburyo bwo kugenzura neza igipimo cya solvent-to-resin kuri lacquer ya nitrocellulose. Aya makuru yihuse kandi ataziguye atuma ibara rikwirakwira neza kandi akarinda guhindagurika kw’urumuri bitewe n’ubusumbane bw’ibinyabutabire - ni ingenzi cyane iyo ukoresheje ibinyabutabire byinshi bishyuha kugira ngo bikoreshwe mu nganda. Gupima umurongo bikuraho gutinda gutangwa mu ngero z’intoki, akenshi bigatera ingaruka zikomeye mu buryo bwo gukwirakwiza ibara ku irangi no kurimbika.
Igipimo cy’ubucucike cya Lonnmeter gipima amasaha 24/7, gikuraho gushingira ku igenzura rya laboratwari rikorwa buri gihe. Gusoma ubucucike bw’ingufu byihuse bihagarika amatsinda y’ibitajyanye n’amategeko mbere yuko bikomeza kuzuza—ni ingenzi cyane ku irangi rinini rikozwe na nitrocellulose lacquer na polymeri bishingira ku bucucike nyabwo.
Gukurikirana buri gihe bituma habaho guhindura vuba uburyo bwo guhitamo irangi ry’ibinyabutabire bitewe n’uburyo ibintu bihinduka mu buryo bufatika. Ibi byemeza ko ibintu byose bihora bihinduka, koroshya ubwiza bw’urumuri, ndetse no kuba imiterere ya filime imwe ndetse no mu gihe cy’ibikorwa binini.
Saba ikiguzi cya Lonnmeter inline density meter kugira ngo ugenzure ikoreshwa rya nitrocellulose lacquer. Gerageza guhindura neza solvents zishyuha cyane kugira ngo zikoreshwe mu nganda, komeza uburyo bwiza bwo gukwirakwiza irangi n'amabara, kandi wongere ubwiza bw'amabara ukoresheje ubwiza bwinshi bushingiye kuri nitrocellulose lacquer.
