Kutheni kuhlala kukho umahluko wombala phakathi kwesampulu yelaphu kunye nesampulu enkulu?

1. Umqhaphu wombala owahlukileyo
Ngaphambi kombala, ilaphu lepotton yendalo kufuneka lihlanjululwe okanye lihlanjululwe, kwaye isampuli encinci ayinakunyangwa kwangaphambili, okanye indlela yokucubungula isampuli encinci ingahluka kwimveliso yesampuli enkulu kwi-workshop.Umswakama welaphu lomqhaphu wendalo uhlukile, kwaye ukufuma okwahlukileyo kwesampulu encinci kunempembelelo enkulu.Ngenxa yokuba umthamo wokufuma wahlukile, ukuweyisha kwahlukile.Ngesi sizathu, kuyafuneka ukuba ilaphu lomqhaphu lendalo lesampulu kufuneka lifane ncakasana nelaphu lomqhaphu eliveliswe kwindawo yokusebenzela.

2. Umahluko wedayi
Nangona iidayi ezisetyenziselwa isampulu encinci kunye nedayi esetyenziselwa isampulu enkulu yohlobo olufanayo kunye namandla, amanani ebhetshi ahlukeneyo okanye ubungakanani obungachanekanga besampulu encinci inokubangela umahluko phakathi kwesampulu encinci kunye nesampulu enkulu.Kwakhona kunokwenzeka ukuba iidayi ezisetyenziselwa ukuveliswa kweesampuli ezinkulu ziye zaxutywa kwaye zimanzi, kwaye ezinye iidayi aziqinisekanga, okubangela ukuhla kwamandla.

3. I-pH yokuhlamba idayi iyahluka
Ngokubanzi, kuchaneke ngakumbi ukubamba ixabiso le-pH yebhafu yedayi kwiisampulu ezincinci, ngelixa ixabiso le-pH leisampulu ezinkulu lingazinzanga okanye akukho sithintelo se-asidi-base esongeziweyo ngexesha lokwenziwa kweesampulu ezinkulu.Ngenxa ye-alkalinity ye-steam ngexesha lombala, ixabiso le-pH liyenyuka ngexesha lokuveliswa kweesampuli ezinkulu, kwaye ezinye iidayi ezisasaza njengeqela le-ester, iqela le-amido, iqela le-cyano, njl njl. i-hydrolyzed phantsi kweemeko eziphezulu ze-alkaline.Kukwakho ezinye iidayi ezinamaqela e-carboxyl anokwenziwa ionized phantsi kweemeko zealkaline, ukunyibilika kwamanzi kunyuswa, kwaye izinga lokudaya liyancitshiswa.Xa ixabiso le-pH leedayi ezininzi ezisasazwayo li-5.5-6, ukugqitywa kombala kuqhelekileyo kwaye kuzinzile, kwaye izinga lokudaya liphezulu.Nangona kunjalo, xa ixabiso le-pH linyuka, umbala uyatshintsha.Njengokusabalalisa kunye nomnyama we-S-2BL, ukusabalalisa i-HGL eluhlaza okwesibhakabhaka emnyama, ukusabalalisa i-gray M kunye nezinye iidayi xa ixabiso le-pH lingaphezulu kwe-7, umbala utshintsha ngokucacileyo.Ngamanye amaxesha ilaphu lomqhaphu lombala wendalo alihlanjwanga ngokupheleleyo kunye ne-alkaline emva kokunyangwa kwangaphambili, kwaye ixabiso le-pH lebhafu yokudaya liyanda ngexesha lokufaka umbala, elichaphazela ukugqiba kombala.

Abanye, ngaba unyango lwangaphambili lwelaphu lomqhaphu lwendalo lufakwe ngaphambili?
Ukuba isampuli enkulu ilaphu yomqhaphu yombala iye yamiliselwa ngaphambili, ilaphu lelaphu lomqhaphu lesampulu elincinane alizange lenziwe ngaphambili, kwanesampulu enkulu kunye nesampulu encinci ziye zamiliselwa ngaphambili, kwaye iqondo lobushushu lokumisela lahlukile, elinokuthi kananjalo. kubangela ukufunxa kombala okwahlukileyo.

4. Impembelelo yomlinganiselo wotywala
Kuvavanyo oluncinane lwesampulu, umlinganiselo wokuhlambela udla ngokuba mkhulu (1:25-40), ngelixa umlinganiselo wokuhlambela omkhulu wesampulu uyahluka ngokwezixhobo, ngokubanzi 1:8-15.Ezinye iidayi ezisasazekileyo azixhomekekanga kumlinganiselo wokuhlambela, kwaye ezinye zixhomekeke ngakumbi, ukuze umehluko wombala ubangelwa yimilinganiselo yokuhlamba eyahlukeneyo yesampuli encinci kunye nesampuli enkulu.

5. Iziphumo ze-post-processing
I-post-processing enye yezizathu ezichaphazela ukuhluka kombala.Iphakathi kakhulu kwaye imnyama.Ukuba awuyibuyisi kwaye uyicoce, ngaphezu kobukho bombala odadayo, kunokuchaphazela ukugqiba umbala kunye nokuvelisa ukungafani kombala othile.Ngoko ke, ukucocwa kokunciphisa kufuneka kuhambelane nesampuli encinci kunye nesampuli enkulu.

6. Isiphumo sokubeka ubushushu
Ukusasaza idayi kunokohlulwa kuhlobo lobushushu obuphezulu, uhlobo lobushushu obuphakathi kunye nohlobo lobushushu obuphantsi.Uhlobo olufanayo lwedayi kufuneka lukhethwe xa kuhambelana nombala.Kwimeko yohlobo lobushushu obuphezulu kunye nohlobo lobushushu obuphantsi obuhambelana nombala, iqondo lokushisa akufanele libe phezulu kakhulu ngexesha lokubeka ubushushu, ukwenzela ukuba ugweme ukushisa okugqithisileyo, okuya kubangela ukuba ezinye iidayi zibe yi-sublime kwaye zichaphazele ukugqitywa kombala, okubangela ukungafani kombala..Iimfuno zeemeko zokumisela isampuli encinci kunye nesampulu enkulu ngokusisiseko ziyafana.Ngenxa yokuba i-pretreatment isetyenzisiwe okanye hayi, iimeko zokumisela (ubushushu) zinempembelelo enkulu ekufunjweni kombala wepolyester (inqanaba elikhulu lokuseta, ukudaya kusezantsi, ngoko ke ilaphu elincinci lesampulu kufuneka lihambelane nelikhulu. isampuli (oko kukuthi, sebenzisa phambi kwemveliso. Iworkshop isemi-finished product replica).
