Ngokubhekiselele kwizinto zeplastiki ezichaphazelekayo, kukho iindlela ezahlukeneyo zokukhetha kwiimarike. Isixhobo ngasinye sineempawu ezikhethekileyo kunye nezicelo, ngoko kubalulekile ukuqonda ukungafani kwaye ukhethe izinto ezifanelekileyo kwiimfuno zakho ezithile. Kule post blog, siza kuxoxa umahluko phakathiIphepha lePPkunye nebhodi yePP, izinto ezimbini ezithandwayo zeplastiki ezisetyenziswa ngokubanzi kumashishini ahlukeneyo.
Zombini iphepha lePP kunye nebhodi yePP zenziwe ngepolypropylene, i-polymer ye-thermoplastic eneempawu ezibalaseleyo. Eyaziwayo ngokuchasa ukudinwa okuguquguqukayo kunye nokumelana nobushushu obugqwesileyo, i-polypropylene ifanelekile kwizicelo ezifuna ukuqina kunye nokumelana nobushushu obuphezulu.
Umahluko omkhulu phakathi kwephepha lePP kunyeIbhodi yePPilele kwiimpawu zabo zomzimba.Iphepha lePPlicwecwe leplastiki elicekethekileyo elinokuqina okuphezulu kunye nokomelela komphezulu. Zihlala zisetyenziselwa iinjongo zokupakisha njengoko zibonelela ngokhuseleko olubalaseleyo kwaye zixhathisa ukunxiba kunye ne-oxidation. Amaphepha e-PP nawo ayaziwa ngokumelana neekhemikhali eziphezulu, okwenza ukuba afaneleke kwizicelo kwishishini lemichiza.
Kwelinye icala, ibhodi yePP ijiyile kwaye yomelele kunephepha lePP. Ngokuqhelekileyo zisetyenziswa kwizicelo ezifuna amandla aphezulu kunye nokuqina, okufana neempawu, imiboniso kunye nezixhobo zesakhiwo. Ibhodi yePP ikwanayo nokugoba ukudinwa kunye nokumelana nobushushu okulungileyo, kufana nephepha lePP.
Nangona zombini iphepha lePP kunyeIbhodi yePPzineempawu ezithile eziqhelekileyo, kuyimfuneko ukunikela ingqalelo kwiiyantlukwano kwimida yazo. Iphepha le-PP lilula ukuba libe brittle kubushushu obuphantsi kwaye alinako ukumelana nemozulu. Zikwangumngeni kwiivanishi kunye neeglues, kwaye azikwazi ukudityaniswa ngamaza aphezulu. Kwelinye icala, iiphaneli zePP nazo zinezithintelo kunye nobunzima bokupenda kunye nokudibanisa.
Xa ukhetha phakathi kwephepha lePP kunye nebhodi yePP, kubalulekile ukuqwalasela iimfuno zakho ezithile kunye nesicelo esijoliswe kuyo. Ukuba ufuna imathiriyeli ebhityileyo kwaye ebhetyebhetye enokumelana neekhemikhali okugqwesileyo, iphepha lePP liya kuba lolona khetho lufanelekileyo. Kwelinye icala, ukuba ufuna imathiriyeli eyomeleleyo enamandla amakhulu kunye nokuqina,Ibhodi yePPiya kufaneleka ngakumbi.
Ngamafutshane, zombiniIphepha lePPkunye nebhodi yePP zizinto zeplastiki zenjongo ngokubanzi ezineempawu zazo ezizodwa kunye nokusetyenziswa. Nangona babelana ngeempawu eziqhelekileyo, ezifana nokuchasana nokukhathala okuguquguqukayo kunye nokushisa, kubalulekile ukuqwalasela imida yabo xa usenza isigqibo. Ngokuqonda umahluko phakathi kwephepha lePP kunye nebhodi yePP, unokwenza ukhetho olunolwazi kwaye ukhethe ezona zinto zifanelekileyo kwiimfuno zakho ezithile.
