Isingeniso
I-PolyButylene Velceinate (PBS) akuyona nje enye ipulasitiki; Kuyindlela yokuguqula isayensi yezinto ezisetshenzisiwe. Njengoba izimboni zibhekene nokukhathazeka okwandayo kwemvelo, indawo yokubuka izinto zisezintweni ezinikezela ukusebenza ngaphandle kokunciphisa umthwalo wemvelo. I-PBS ifanela lokhu kulandisa ngokuphelele. Lokhu okuthunyelwe kwebhulogi kuhlose ukwehla kulokho i-PB, izakhiwo zayo eziphawuleka, izinhlelo zokusebenza, nokuthi kungani zithola ukuqashelwa ezimbonini ezahlukahlukene.
Yini i-polybutylene imunca (PBS)?
I-PolyButyleneneune Susceinate, eyaziwa ngokuthi yaziwa njenge-PBS, iyi-Aliphatic Polyester enesakhiwo samakhemikhali esiyingqayizivele esiyibeka ngaphandle kwamapulasitiki wendabuko. Ngokungafani nama-plastitics ajwayelekile afana ne-polyethylene noma i-polypropylene, ama-PB enziwa nge-polymerization ye-suscinic acid kanye ne-1,4-butanediol. Lokhu ukwakheka kwamakhemikhali kunomthelela emandleni ayo emishini kanye ne-biodegradeality.
Enye yezici zokuma kwama-PB ziwukunye okuhlukahlukene. Ingacutshungulwa ngezindlela ezijwayelekile zepulasitiki zokukhiqiza, kufaka phakathi ukubumba okuhlanganisiwe, ukukhishwa, nokushaya ngamandla. Izinto ezibonakalayo zibuye zikhombise ibhalansi enhle kakhulu yamandla ashukumisayo, ukuqina okushisayo, nokumelana nomthelela. Empeleni, ama-PBS aletha okuhle kakhulu emhlabeni wonke: ukuqina kwamapulasitiki ajwayelekile kanye ne-biodegracabilibility yezinto eziningi ze-eco-friendly.
Kungani i-PBS ibalulekile
Emhlabeni ngokuya ngokuqaphela umthelela wayo wezemvelo, i-PBS isebenza njengebhuloho elibalulekile phakathi kokuqina kanye nokusebenza kwezimboni.
Izinzuzo Zemvelo
Okokuqala, i-PBS iyi-biodegradable. Ngokungafani namapulasitiki wendabuko athatha amakhulu eminyaka ukubola, ama-PBs angadiliza ngokushesha okukhulu lapho evezwa izimo ezifanele. Ucwaningo lwakamuva lukhombisile ukuthi ama-PB angabola kungakapheli izinyanga ezimbalwa ngaphansi kwezimo zomquba wezimboni, okwenza kube yindlela ehlakaniphile yemikhiqizo esetshenziswayo edinga ukulahlakala ngaphandle kokulimala kwezemvelo okukodwa.
Izakhiwo Zemishini
I-PBS ayisiyena nje enobungane; Iphinde ithole okuphezulu ekusebenzeni. Izinto zibonisa amandla amahle ashubile, acishe aqhathaniswe ne-polyethylene, okwenza kube nzima ukusetshenziswa kwansuku zonke. Ukuqina kwayo okushisayo kuvumela ukuthi kubekezelele uhla lwamazinga okushisa, kuvame ukudlula lokho kwe-polystyrene, okwenza kuguquguquke ngakunye kwezicelo. Lezi zinhloso zemishini zikwenza kungaphezu kokumane 'kube luhlaza’ okunye; Ama-PB aqine ngokweqiniso futhi angathatha isikhundla sepulasitiki yendabuko ngezicelo eziningi ngaphandle kwekhwalithi enikelayo.

Izicelo ze-PBS
Izakhiwo ezihlukile ze-PBS zenza ukuthi zivumelane nezimo eziguquguqukayo ngaphesheya kwezimboni kanye nezicelo. Ngezansi ezinye izindawo ezibalulekile lapho ama-PB enza uphawu lwawo.
Ukupakisha
Ngamandla ayo amahle ashubile kanye ne-biodegradeability, i-PBS yisinqumo esinamandla sezinto zokupakisha. Kuthandwa ikakhulukazi ekuphaphekeni kokudla lapho ukuphepha kwako kanye nemvelo ye-biodegradable kunikeza umphetho.
Amafilimu Ezolimo
I-biodegrade ye-PBS yenza kube fanele ukusetshenziswa kumafilimu ezolimo. Lawa mafilimu angashiywa ukuze aboleke ngokwemvelo emkhakheni, anciphise imfucuza kanye nomsebenzi ohilelekile ekususeni kwabo.
Izingxenye Zezimoto
Embonini eqhubekela ekusimeni, ama-PBS athola izinhlelo zokusebenza ezingxenyeni zangaphakathi zezimoto. Izakhiwo zayo zemishini eziqinile zikwenza kufanelekile izingxenye ezidinga ukuqina kanye nokumelana ukuze ugqoke futhi aklebhu.
Ezogesi
Yize kungejwayelekile, i-PBS nayo iyahlolwa kumkhakha we-elekthronikhi izingxenye ezinjengezixhumi noma ukuhlanganisa, ukuhlanganisa amandla okwenziwa ngomshini ngomthelela omncane kwezemvelo.
Ukuhambisana nokulawula
Imithetho yokuzulazula iyisici esijabulisayo lapho ukhetha izinto zohlelo lokusebenza, futhi i-PBS ayikho okuhlukile. Nakhu ukuthi i-PBS ibeka kanjani ukulwa nezindinganiso ezijwayelekile zokulawula:
I-FDA Ukuhambisana
Kuzinhlelo zokusebenza ezihlobene nokudla, i-U.S. Food and Drug Administration (FDA) isetha imihlahlandlela eqinile yokuphepha ngokwezinto ezibonakalayo. Ama-PBS avame ukuhambisana nalokhu, ikakhulukazi ikhodi ye-FDA ye-Federal Regulations Isihloko 21, okwenza kube inketho ephephile yokupakishwa kokudla.
Izindinganiso ZaseYurophu
I-PBS ibuye ivumelanise kahle namazinga we-European Union, imvamisa ukuhlangana nezidingo zemithethonqubo yokufinyelela, ebaluleke kakhulu ngezinto ezisetshenziselwa izinhlelo ezihlukene ezwenikazi lonke.
Isitifiketi se-ISO
Ngomsebenzi ofanelekile, ama-PBs avame ukuthola isitifiketi se-ISO. Le Averal International iwuphawu lwekhwalithi kanye nokuvumelana, okubonwa kabanzi kwizimboni.
Ul kanye nezinye izivivinyo
Okunye ukuhlola okukhwalithi, njenge-UL (Labors Laboratories) amazinga akhona, asebenza nama-PBS, ikakhulukazi uma kusetshenziswa kuma-elekthronikhi nezimoto.
Izinselelo Nokulinganiselwa
Ngenkathi ama-PBS enikeza inzuzo yezinzuzo, kubalulekile ukuthi ucabangele nezinselelo kanye nemikhawulo eza nokusetshenziswa kwayo.
Izindleko
Enye yezingqinamba eziyinhloko izindleko. I-PBS ngokuvamile ibiza kakhulu kunamapulasitiki wendabuko. Lokhu kungaba yisithiyo esikhulu sezinkampani ezibheke ukwenza ushintsho oluphelele ezintweni ezizinzile kakhulu.
Ukutholakala Kwemakethe
Yize ama-PB athola ukugcwala, ukungena kwawo kwemakethe akusanzi kakhulu njengalezo zipulasitiki ezijwayelekile. Lokhu kunciphisa izinketho zokuthenga ngobuningi noma okuhlukahlukene okukhethekile kwama-PB.
Ukufaneleka ngokwezinto ezibonakalayo
Ngenkathi i-PBS inikeza izakhiwo ezinhle zemishini, kungenzeka ingalungele zonke izinhlelo zokusebenza. Ukusetshenziswa okuthile okukhethekile kungadinga izakhiwo ukuthi ama-Pbs anawo ngokwemvelo, adinga ukuxubana noma ukuguqulwa okungase kwenyuse izindleko.
Ikusasa lama-PBS
Njengoba sibheka phambili, ikusasa libonakala lithembisa i-polybutyleneen ancace. Ngezansi kunezindlela ezithile nezinkomba zokucwaninga ezisho ukubaluleka kwayo okukhulayo.
Izitayela ezizayo
I-Bioplastics iyikusasa, futhi i-PBS yi-frontrunner kulolu shintsho. Imibiko yemakethe iphakamisa ukukhula okuqinile kusidingo se-PBS eminyakeni ezayo, ikakhulukazi emaphaketheni okudla kanye nezimboni zezimoto.
Izinkombandlela Zokucwaninga
Ucwaningo oluqhubekayo lugxile ekuthuthukiseni izakhiwo zemishini ze-PB ngokusebenzisa izinhlanganisela nama-composites, okwenza kuguquguquke ngokwengeziwe. Kuyaqhubeka nemizamo yokuletha izindleko zokukhiqiza, okwenza kube kutholakale kalula ekutholweni kwemboni ebanzi.
Isiphetho
I-PolyButylene Velceinate (PBS) iyisitatimende esibaluleke kakhulu, esihlanganisa amandla emishini ngokwazi kwemvelo. Ukusuka kumakhemikhali wayo wekhemikhali ekuguquguqukeni kwayo kanye nezicelo, ama-PBS anikeza isixazululo esilinganiselayo kuzinselelo zezimboni eziningi ezibhekana nazo namuhla. Njengoba ukukhathazeka kwezemvelo kuyanda, iqhaza lezinto ezizinzileyo ezinjenge-PB zizobe zibaluleke kakhulu.
