Wonke umntu uyazi ukuba umatshini wekomityi yephepha luhlobo lwemveliso yekomityi yephepha, eneempawu zokusebenza kakuhle kunye nokubumba okulungileyo, okukwazi ukuhlangabezana neemfuno zoluntu.Ngaba uyazi ukuba iikomityi zephepha ezenziwe wax zaqala nini ukuveliswa?Zeziphi iimpawu zomatshini wokwenza ikomityi?Oku kulandelayo luluhlu, izixhobo zemveliso kunye neempawu zoomatshini bekomityi yephepha ukusuka kubenzi bekomityi yephepha eHongxin.Ukuhlelwa kweekomityi zephepha eziveliswe nguumatshini wekomityi yephepha:
1. Iikomityi zephepha ezenziwe nge-wax Ngo-1932, iiseti ezimbini zeekomityi zephepha, ezinomgangatho ogudileyo unokuprintwa ngeepatheni ezahlukeneyo ezigqwesileyo, unokuphucula umphumo wopapasho.Ngakolunye uhlangothi, i-waxing yekomityi yephepha inokuphepha ukudibanisa ngokuthe ngqo phakathi kwesiselo kunye nephepha, ukukhusela ukunamathela kweglue, kunye nokuphucula ukuqina kwendebe yephepha;kwelinye icala, iphinda ikhulise ubukhulu bodonga olusecaleni, oluphucula kakhulu amandla ekomityi yephepha kunye nokunciphisa ixesha lokuvelisa.Ubungakanani bephepha elifunekayo kwiikomityi ezinamandla, ngaloo ndlela kuncitshiswa iindleko zokuvelisa.Njengoko iikomityi zephepha le-wax ziba zizikhongozeli zesiselo esibandayo, abantu bafuna isikhongozeli sesiselo esishushu esifanelekileyo.Kodwa iziphuzo ezishushu ziya kunyibilika umgca we-wax kwindawo yangaphakathi yendebe, kwaye ibhondi iya kwahlula.Ke ngoko, iikomityi zephepha le-wax ngokubanzi azifanelekanga ukubamba iziselo ezishushu.
2. Ukuze kwandiswe uluhlu lwezicelo zeekomityi zephepha, iikomityi zephepha ezinodonga oluphindwe kabini zaqaliswa ngo-1940. Le ndebe yephepha ayilula nje ukuyiphatha, kodwa ingasetyenziselwa ukubamba iziselo ezishushu.Ukusukela ngoko, abavelisi baye bagquma iikomityi nge-latex ukuvala “ivumba lekhadibhodi” yephepha kwaye baphucule iimpawu zekomityi zokungavuzi.Iikomityi ze-wax ezinomgca omnye ezine-latex yokwambathisa zisetyenziswa ngokubanzi ukubamba ikofu eshushu koomatshini bokuthengisa.
3. Iikomityi zephepha ezifakwe ngeplastikiEzinye iinkampani zokutya ziye zaqalisa ukugqoka ikhadibhodi nge-polyethylene ukunyusa umqobo kunye nokuqina komoya kwepakethe yephepha.Ekubeni indawo yokunyibilika ye-polyethylene iphezulu kakhulu kune-wax, iikomityi zephepha ezifakwe nge-polyethylene zingasetyenziselwa ukubamba iziphuzo ezishushu, ezinokusombulula ingxaki yokuba ukunyibilika kwezinto zokugubungela kuchaphazela umgangatho wemveliso.Ngelo xesha, i-polyethylene yokugqoka ilula kuneyokuqala i-wax, iphucula ukubonakala kweekomityi zephepha.Ukongeza, itekhnoloji yayo yokucubungula iyabiza kwaye ikhawuleza kuneendlela zisebenzisa i-latex coatings.
