Ukuqonda umehluko phakathi kwezikhwama ezingalukiwe nezikhwama zepulasitiki kubalulekile ekwenzeni izinqumo ezinolwazi mayelana nokukhetha okusimeme. Zombili izinhlobo zezikhwama zinesethi yazo yezinzuzo kanye nokubi, ezinomthelela endaweni ezungezile, ukuqina kwazo, nokusebenza kwazo ngezindlela ezihlukahlukene.
Izikhwama ezingalukiwe ngokuvamile zenziwe nge-polypropylene, uhlobo lwepulasitiki oluphothwa lube imicu futhi luhlanganiswe ndawonye. Lezi zikhwama zaziwa ngokuqina kwazo, ukusebenziseka kabusha, kanye nomthelela ophansi kwezemvelo uma kuqhathaniswa nezikhwama zepulasitiki zendabuko. Angasetshenziswa kabusha izikhathi eziningi futhi avame ukugaywa kabusha, okuwenza abe inketho esimeme ngokuhamba kwesikhathi.
Ngakolunye uhlangothi, izikhwama zepulasitiki zenziwe nge-polyethylene, uhlobo lwepulasitiki olutholakala kumafutha ezinto ezimbiwa phansi. Ayisindi, ashibhile ukuwakhiqiza, futhi alungele ukusetshenziswa okukodwa. Nokho, umthelela wazo kwezemvelo ubalulekile. Izikhwama zepulasitiki zifaka isandla ekungcoleni, kuthatha amakhulu eminyaka ukubola, futhi ngokuvamile azivuselelwa kahle, okuholela ekulimaleni kwemvelo okusabalele.
Okugxilwe kakhulu kule bhulogi ukuqhathanisa izikhwama zepulasitiki ezingalukiwe kanye nomthelela wazo endaweni, ukuqina, nokusebenza kwazo. Sizohlola ukuthi uhlobo ngalunye lwesikhwama lusebenza kanjani kulezi zindawo futhi sinikeze imininingwane ukuze sikusize wenze ukukhetha okuzinzile. Ukuqonda lo mehluko kungasiza ekunciphiseni ukulimala kwemvelo futhi kukhuthaze ukuziphatha kwabathengi abanomthwalo wemfanelo.
I. Ukuqonda Izikhwama Ezingalukiwe
A. Incazelo kanye Nezisetshenziswa
Izikhwama ezingalukiwe ziwuhlobo lwesikhwama sokuthenga esisebenziseka kabusha esenziwe nge-non-woven polypropylene (PP). Ngokungafani nezindwangu ezilukiwe zendabuko, izinto ezingezona ezilukiwe zenziwe ngokuhlanganisa imicu kusetshenziswa izinqubo zamakhemikhali, ezomshini, zokushisa, noma ezincibilikayo. Lokhu kubangela indwangu eqinile, engasindi, futhi engangeni manzi.
Ukwakheka
Izikhwama ezingezona ezilukiwe ngokuyinhloko zakhiwe nge-polypropylene, uhlobo lwepulasitiki eyaziwa ngamandla ayo kanye nokuguquguquka. Imicu ekulezi zikhwama iyaphothwa bese ihlanganiswa, okwenza indwangu elingisa ukubukeka nomuzwa wezinto ezilukiwe ngaphandle kwesidingo sokulukwa kwangempela.
Izinto Ezivamile
I-Polypropylene yinto evame ukusetshenziswa kakhulu ezikhwameni ezingalukiwe. Inikeza izinzuzo ezimbalwa:
Ukuqina : Amafayibha e-Polypropylene akha indwangu eqinile, engadabuki.
Ukumelana Namanzi : Izikhwama ze-PP ezingalukiwe zingamelana namanzi, zizenze zilungele izimo zezulu ezihlukahlukene.
Ukusebenziseka kabusha : Lezi zikhwama zingasetshenziswa kabusha izikhathi eziningi, kunciphisa isidingo samapulasitiki asetshenziswa kanye.
I-Eco-Friendliness : I-Polypropylene iyakwazi ukugaywa kabusha, engasiza ekunciphiseni umthelela wendawo uma ilahlwa ngendlela efanele.
B. Inqubo Yokukhiqiza
Ukukhiqizwa kwezikhwama ezingalukiwe kuhilela uchungechunge lwezinyathelo eziguqula izinto ezingavuthiwe zibe izikhwama ezihlala isikhathi eside, ezisebenziseka kabusha. Le nqubo ihlukile ekwalukeni kwendabuko, incike kumasu ahlanganisa imicu ngaphandle kwesidingo sokuluka noma ukunitha.
Uhlolojikelele Lwenqubo Yokukhiqiza Isikhwama Esingalukiwe
Izikhwama ezingezona ezilukiwe zenziwe ngokuyinhloko ngemicu ye-polypropylene (PP). Ukukhiqizwa kuqala ngokuncibilika kwamapellets e-polypropylene, abese ekhishwa abe imicu emihle. Le micu yendlalwa ngokungahleliwe ukwenza isakhiwo esifana newebhu. Le webhu ibe ingaphansi kwezinqubo zokuhlanganisa ukuze kudaleke indwangu yokugcina.
Amasu Asetshenziswa
I-Heat Bonding : Enye yezindlela ezivame kakhulu ukuhlanganisa ukushisa. Kule nqubo, iwebhu ye-polypropylene fibers idluliswa ngama-roller ashisayo. Ukushisa kuncibilikisa imicu ezindaweni lapho kuxhumene khona, kuhlanganiswe ndawonye. Le ndlela iyasebenza futhi ibangela indwangu eqinile, ehlangene.
I-Chemical Bonding : Enye indlela i-chemical bonding, lapho i-ejenti yokubopha isetshenziswa kuwebhu ye-fiber. Amakhemikhali akha izibopho phakathi kwemicu njengoba yomile noma yelapha. Le ndlela ivumela ukuguquguquka ekulungiseni amandla nokuthungwa kwendwangu.
I-Mechanical Bonding : Ukubopha ngemishini, njengokubhoboza inaliti, kuhilela ukubopha imicu ngokomzimba. Izinaliti zibhoboza ku-fiber web, zixhumanisa imicu ngomshini. Le nqubo ithuthukisa amandla nokuqina kwendwangu.
II. Ukuqonda Izikhwama Zepulasitiki
A. Incazelo kanye Nezisetshenziswa
