Njengoko ingcamango yophuhliso oluzinzileyo ingena kwishishini lobuhle, iimpawu ezininzi zigxile ekusebenziseni izixhobo ezinobuhlobo nokusingqongileyo kwiipakethe zazo. I-PMMA (polymethylmethacrylate), eyaziwa ngokuba yi-acrylic, sisixhobo seplastiki esisetyenziswa kakhulu kwiipakethe zobuhle, kwaye sithandwa kakhulu ngenxa yokucaca kwayo okuphezulu, ukumelana nempembelelo, kunye neempawu zokumelana ne-ultraviolet (UV). Nangona kunjalo, ngelixa igxile kubuhle, ubuhlobo bendalo be-PMMA kunye namandla ayo okuphinda isetyenziselwe izinto zitsala ingqalelo kancinci kancinci.
Yintoni i-PMMA kwaye kutheni ifanelekile ukupakishwa kwezithambiso?
I-PMMA yinto eyenziwe nge-thermoplastic ebonakala kakuhle, evumela ukukhanya okungaphezulu kwe-92% kungene, inika isiphumo esicacileyo esifana neseglasi. Kwangaxeshanye, i-PMMA inokumelana kakuhle nemozulu kwaye ayithambekeli ekubeni tyheli okanye iphele nokuba sele ibekwe kwimitha ye-UV ixesha elide. Ke ngoko, uninzi lwezinto zokuthambisa eziphezulu zikhetha ukusebenzisa ukupakisha kwe-PMMA ukuphucula ubume kunye nobuhle bemveliso. Ukongeza ekubukekeni kwayo, i-PMMA ikwamelana neekhemikhali, iqinisekisa uzinzo lwezinto zokuthambisa ngexesha lokugcinwa.
Izicelo eziqhelekileyo zokupakisha i-PMMA ziquka:
Izivalo zebhotile ye-serum: I-PMMA inokubonakalisa ubume obufana neglasi, obuhambelana nokubekwa kweemveliso eziphezulu ezifana ne-serum.
Iibhokisi zomgubo kunye nokupakishwa kwekhrimu yobuhle: Ukumelana nempembelelo kwe-PMMA kwenza iimveliso zikhuseleke ngakumbi ngexesha lokuthuthwa nokusetyenziswa kwemihla ngemihla.
Iigobolondo ezicacileyo: Iigobolondo ezicacileyo zeemveliso ezifana neelipstick kunye neziseko, umzekelo, zibonisa umbala womxholo kwaye zongeza imvakalelo ephezulu yephakheji.
Ingakanani i-PMMA enokukwazi ukuyisebenzisa kwakhona?
Phakathi kwe-thermoplastics, i-PMMA inamandla okuphinda isetyenziswe, ingakumbi kuba ukuzinza kwayo kwiikhemikhali kuyivumela ukuba igcine iipropati ezintle zomzimba nokuba sele iphinda isetyenziswe izihlandlo ezininzi. Nazi iindlela ezimbalwa zokuphinda isetyenziswe ze-PMMA kunye namathuba azo okusetyenziswa ekupakisheni ubuhle:
Ukuphinda kusetyenziswe ngoomatshini: I-PMMA ingaphinda isetyenzwe ngoomatshini ngokuyityumza, ukuyinyibilikisa, njl.njl. ukuze yenziwe ibe yiphakheji entsha ye-PMMA okanye ezinye iimveliso kwakhona. Nangona kunjalo, i-PMMA ephinda isetyenzwe ngoomatshini inokwehla kancinci kumgangatho, kwaye ukusetyenziswa kwakhona kwiphakheji yobuhle ephezulu kufuna ukucutshungulwa kakuhle.
Ukuphinda usebenzise iikhemikhali: Ngokusebenzisa iteknoloji yokubola kweekhemikhali, i-PMMA ingahlulwahlulwa ibe yi-monomer yayo i-MMA (i-methyl methacrylate), enokuthi emva koko yenziwe i-polymer ukuze kwenziwe i-PMMA entsha. Le ndlela igcina ubunyulu obuphezulu kunye nokucaca kwe-PMMA, okwenza ukuba ifaneleke ngakumbi kwimveliso yokupakisha izithambiso ezikumgangatho ophezulu. Ukongeza, ukuphinda usebenzise iikhemikhali kunobuhlobo nokusingqongileyo ekuhambeni kwexesha kunokuphinda usebenzise oomatshini, kodwa ayikasetyenziswa kakhulu kwicandelo lezithambiso ngenxa yeendleko zayo eziphezulu kunye neemfuno zobugcisa.
Imfuno yemarike yezicelo ezizinzileyo: Njengoko kukho umkhwa okhulayo wokukhusela okusingqongileyo, iimpawu ezininzi zobuhle ziqala ukusebenzisa izixhobo ze-PMMA ezisetyenzisiweyo ukupakisha. I-PMMA esetyenzisiweyo isondele kakhulu kwizinto ezingasetyenziswanga ngokubhekiselele ekusebenzeni kwayo kwaye inokunciphisa ngokufanelekileyo ukusetyenziswa kwezinto eziluhlaza, ngaloo ndlela inciphisa umngcipheko wekhabhoni. Iimpawu ezininzi ngakumbi zifaka i-PMMA esetyenzisiweyo kuyilo lwemveliso yazo, engahlangabezani neemfuno zobuhle kuphela, kodwa ikwahambelana nomkhwa wokukhusela okusingqongileyo.
Amathemba exesha elizayo okuphinda kusetyenziswe i-PMMA kwiipakethe zezimonyo
Nangona i-PMMA inamandla amakhulu okuphinda isetyenziswe kwiipakethe zobuhle, imingeni isekho. Okwangoku, iteknoloji yokuphinda isetyenziswe ye-PMMA ayisasazeki ngokwaneleyo, kwaye ukuphinda isetyenziswe kweekhemikhali kuyabiza kwaye kuncinci. Kwixesha elizayo, njengoko iteknoloji iqhubela phambili kwaye iinkampani ezininzi zityala imali kwiipakethe ezinobuhlobo nokusingqongileyo, ukuphinda isetyenziswe kwe-PMMA kuya kuba luncedo ngakumbi kwaye kuqheleke.
Kule meko, iimpawu zobuhle zinokukhuthaza uphuhliso oluzinzileyo lokupakisha izithambiso ngokukhetha ukupakisha kwe-PMMA okuphindiweyo, ukuphucula amanyathelo okusingqongileyo kwikhonkco lokubonelela, njl. I-PMMA ayizukuba yinto ethandekayo kuphela, kodwa ikwalukhetho olumele ukudibanisa ukhuseleko lokusingqongileyo kunye nefashoni, ukuze yonke iphakheji incede ekukhuseleni okusingqongileyo.
