Ukhukhwezi Lwe-Impact Nenkazimulo Yenkazimulo Ngokuhlolwa
Xa uhlolile Plexiglass vs Polycarbonate , ukhukhwezi lwe-impact kuqukethe izinkinga eziphelele. Aba-sayensi bezinto bamele lokhu ngokwenza kwabo — ukwazi ukuthatha isivinini ngaphambi kokuthunjwa. I-polycarbonate iyadomine kule ndawo, ihlinza iqiniso elingavamile ekugcineni kususumba esiphakeme.
Ukuhlanya Kwe-Polycarbonate Ekutholeni Impact (250× Acrylic)
Uma kuziwa ekuqhumeni, i-polycarbonate iphakeme ngokuphindwe izikhathi ezingu-250 kunengilazi ye-plexiglass ngenxa yokuthi ama-molecule ayo aguquguqukayo ezingeni elincane. I-Plexiglass yakudala inamaketanga aqinile e-acrylic ayihamba phakathi, kodwa i-polycarbonate empeleni iyanwebeka uma okuthile kuyishaya, njengokungathi i-trampoline isakaza amandla esikhundleni sokuvumela konke ukuba kugqashuke. Yingakho sibona lisetshenziswa kakhulu ezindaweni lapho ukuqhekeza ingilazi kungaba izinto eziyingozi njengalezo zihlangu ezinkulu amaphoyisa azigqokayo ngesikhathi semibhikisho noma amafasitela akhethekile enzelwe ukumelana neziphepho. Okunye ukusebenza kwaselabhorethri nakho kuyakuqinisekisa lokhu - bahlola amashidi anobukhulu obungamasentimitha angu - 5 futhi bathola ukuthi i - polycarbonate yayibambelela lapho ishaywa kaningi ngesando kuyilapho i - acrylic yayisanda kuchitheka ngokushesha. Nakhu okunye mayelana nayo uma kuqhathaniswa nezinye izinto eziphuka kalula: esikhundleni sokuqhekeka ngokuphelele, i-polycarbonate igobeka kancane kuqala bese ibuyela esimweni sayo, okusho ukuthi noma ngabe iyisiphi isakhiwo esiyingxenye yaso ihlala ingashintshiwe ngisho nangemva kokushaywa kanzima.
Ukuthi Iqiniso Lehlukile Kangakanani: Ukupheleka Kwezikhala (Plexiglass) vs Ukuguquka Kwesithelo (Polycarbonate)
Xa kugcinelwa ngokungcolotshelwa, i-Plexiglass ihlukana ngendlela epholile, kanjalo ngenkathi isibhakabhaka sihlupha ngaphandle kokubanjwa kabala kuqala. Oku kutheni yilokhu lokhu kwenzeka: leyo nto enhlekele yahlupha ngamanqaku amancane ahlanzekile xa afinyelela indawo yakhe yokuhlupha. Ngokuphambene, i-polycarbonate ichaza ngendlela eyodwa. Esikhundleni sokulahluka ngokushesha, ikhanda kakhulu, ngamaxesha njengomgama wokuba 130 iphesenti ende kunaleyo yaso gama phambi kokuphela. Le ndlela yokukhanda isuka koko lokhu kukhona ukuba imithombo yethaphelesikhiyi ihamba ngaphandle kwenye esikhundleni sokuhlupha kuphela. Thatha umzekelo wokuthi kusakhe kube lutho xa ubhali basebhasibhola uphazanyiswa ku-Plexiglass kunye ne-polycarbonate. NgePlexiglass, sithola lezi zikreysi ezifanayo nezinkanyezi evela ngaphandle, kodwa i-polycarbonate iphumla kuphela futhi ibe nenqobo. Ngoba yenzeke ukuba ikhande, abasebenzi besayensi banokudala izindawo ezithile kumfanekiso wokuphepha lapho kukhona ukwehlukana okubekiwe, ekhokhela amandla okuphumla ngaphandle kokwakha amaqoshiso athintwayo aphambene nasemfuleni wonke.
Ubunzima Bekhondo: Ubunzima Be-UV, Ukusebenza Kwesithuthi, Nokukhathazeka Kwezulu
Uma ukhetha phakathi Plexiglass vs Polycarbonate kumasebenzi ekhonjeni, kubalulekile ukunzima kwemvelo. Ezimbili izinto ziyaphazanyiswa yi-UV, ubude bezibuko, nempilo, kodwa ubunjalo bawahlukana kakhulu.
Ukukhathaza Kwe-UV Nokugcina Kwezibonakude Ngexesha
I-plexiglass, eyaziwa nangokuthi i-acrylic, ngokwemvelo iyamelana kahle nomonakalo we-UV. Amasonto amaningi agcina cishe u-90% wokucaca kwawo kwangempela ngisho nangemva kokuhlala ngaphandle iminyaka eyishumi ngaphandle kokwelashwa okukhethekile.
