I-Chemical mechanical pulping iyindlela ye-pulping esebenzisa ukwelapha kusengaphambili kwamakhemikhali kanye nokugaya ngomshini ngemva kokwelashwa.Okokuqala, phatha ukwelashwa okuthambile (ukucwilisa noma ukupheka) ngamakhemikhali ukuze ususe ingxenye ye-hemicellulose kumachips okhuni.I-Lignin incane noma cishe ayincibilikisiwe, kodwa isendlalelo se-intercellular siyathamba.Ngemuva kwalokho, i-disc mill isetshenziselwa ukwelashwa ngemuva kokugaya ukhuni oluthambile (noma ama-chips otshani) ukuhlukanisa imicu ibe yi-pulp, ebizwa ngokuthi i-chemical mechanical pulp (CMP).
Umshini we-screw knotter ophindwe kabili usebenza ekudonselweni kanzima kwama-chips okhuni, ama-bamboo chips, izinto zegatsha, utshani berayisi nezinye izinto zokusetshenziswa.Ingakwazi ukucubungula ngokuqondile izinto zokusetshenziswa zibe imicu ye-velvet, futhi ingenziwa ngokuqondile ibe yi-pulp ngezihlungi zokugxilisa kakhulu .
Umshini we-screw knotter ophindwe kabili wakhiwe ikakhulukazi igumbi elinodaka, isisekelo, idivayisi yokuphakelayo, idivayisi yokudlulisela, injini eyinhloko, njll. Ngemva kokuthi injini yehlise isivinini ngesinciphisi, udaka luphushelwa egumbini lokugaya oludaka ngesikulufu, bese liyahlakazeka. zibe imicu yevelvet ngaphansi kokukhuhla okuqinile nokugaya kwepuleti lokugaya.Umshini unesakhiwo esilula, ukufakwa okulula nokugcinwa kalula.
