Note: Sanadihii la soo dhaafay, horumarka degdegga ah ee warshadaha wax soo saarka iyo soo saarista ee adduunka oo dhan ayaa si weyn kor ugu qaaday baahida macaamiisha ee caagagga wax laga beddelay.

Caagagga wax laga beddelay waxaa loola jeedaa alaabada balaastigga ah iyadoo lagu saleynayo caagagga guud ee loo yaqaan 'plastics' iyo caagagga injineernimada ee lagu farsameeyay laguna beddelay qaababka sida buuxinta, isku darka, iyo xoojinta si loo hagaajiyo dib u dhaca ololka, xoogga, caabbinta saameynta, iyo adkaanta.

Caagagga caadiga ah waxay badanaa leeyihiin astaamo iyo cillado u gaar ah. Qaybaha balaastigga ah ee wax laga beddelay ma gaari karaan oo keliya waxqabadka xoogga biraha qaarkood, laakiin sidoo kale waxay leeyihiin cufnaan hoose, adkeysi sare, caabbinta daxalka, caabbinta saameynta sare, xoogga sare, iyo xirashada iska caabbinta. Faa'iidooyin taxane ah, sida gariirka ka hortagga iyo olol-celinta, ayaa ka soo ifbaxay warshado badan, waana wax aan macquul ahayn in la helo walax beddeli karta alaabada balaastigga ah ee baaxadda weyn leh xilligan.

Sanadihii la soo dhaafay, horumarka degdegga ah ee warshadaha wax soo saarka iyo soo saarista ee adduunka oo dhan ayaa si weyn kor ugu qaaday baahida macaamiisha ee caagagga wax laga beddelay.

Sannadkii 2018-kii, dalabka Shiinaha ee caagagga wax laga beddelay wuxuu gaadhay 12.11 milyan oo tan, koror sannad-sannadeed ah 9.46%. Baahida loo qabo balaastigga wax laga badalay ee qaybta baabuurta waa 4.52 milyan tan, waxayna u dhigantaa 37%. Qiyaasta balaastikada wax laga badalay ee qalabka gudaha ee baabuurta ayaa kordhay in kabadan 60%. Maaddaama ay tahay maaddada ugu fudud ee baabuurta miisaanka yar, ma yarayn karto oo keliya tayada qaybaha qiyaastii 40%, laakiin sidoo kale waxay yareyn kartaa kharashyada wax soo iibsiga illaa 40%. .

Qaar ka mid ah codsiyada balaastigyada wax laga beddelay ee ku yaal qaybta baabuurta

Waqtigan xaadirka ah, qalabka PP (polypropylene) iyo wax ka beddelka PP ayaa si ballaadhan loogu adeegsadaa qaybaha gudaha ee baabuurta, qaybaha dibedda iyo qaybaha hoosta ka hooseeya. Wadamada warshadaha baabuurta ee horumarsan, isticmaalka qalabka PP ee loogu talagalay baaskiiladaha ayaa ah 30% dhammaan balaastikada gawaarida, taas oo ah noocyada ugu badan ee loo isticmaalo dhammaan qalabka balaastigga ah ee gawaarida. Sida ku xusan qorshaha horumarinta, sanadka 2020, celceliska bartilmaameedka isticmaalka balaastigga ee gawaarida ayaa gaari doona 500kg / gaari, taasoo ka dhigan in ka badan 1/3 wadarta qalabka gawaarida.

Waqtigan xaadirka ah, weli waxaa jira farqi u dhexeeya Shiinaha soo saareyaasha caagagga wax laga beddelay iyo dalal kale. Jihada horumarka mustaqbalka ee balaastikyada wax laga beddelay waxay leeyihiin dhinacyada soo socda:

1. Wax ka beddelka caagagga guud;

2. Balaastikadaha wax laga beddelay ayaa leh waxqabad sare, waxqabadyo badan oo isku dhafan;

3. Qiimo jaban iyo warshadeyn balaastiig gaar ah;

4. Codsiga tikniyoolajiyadda sare sida farsamada nanocomposite;

5. Cagaar, ilaalinta deegaanka, kaarboon hooseysa iyo dib u warshadaynta caagagga wax laga beddelay;

6. Soosaarida waxyaabo cusub oo tayo sare leh iyo cusbayn gaar ah oo aasaasi ah


Qeyb ka mid ah isticmaalka balaastikada wax laga badalay ee qalabka guryaha

Marka lagu daro qeybta gawaarida, qalabka guryaha sidoo kale waa goob lagu isticmaalo balaastikada wax laga badalay. Shiinaha waa soo saaraha ugu weyn ee qalabka guryaha. Caagagga wax laga beddelay ayaa si ballaadhan loogu isticmaalay qaboojiyeyaasha iyo alaabooyinka kale waagii hore. Sannadkii 2018, dalabkii balaastigga wax laga beddelay ee ku saabsan qalabka guryaha wuxuu ahaa qiyaastii 4.79 milyan tan, oo u dhiganta 40%. Iyadoo la soo saaray alaab heer sare ah, baahida loo qabo balaastigga wax laga beddelay ee ku saabsan qalabka guryaha ayaa si tartiib tartiib ah u kordhay.

Intaas oo keliya maahan, maxaa yeelay balaastikyada wax laga beddelay guud ahaan waxay leeyihiin dahaadh koronto oo wanaagsan, waxay door lama huraan ah ka ciyaaraan aagagga korantada iyo korantada.

Awoodda korantada, adkaysiga dusha sare, iyo adkaysiga mugga ayaa sida caadiga ah si buuxda u buuxin kara shuruudaha alaab-koronto-hooseeya. Waqtigan xaadirka ah, qalabka korontada ku shaqeeya ee koronto-yarida ah ayaa u kobcaya jihada miniaturization, shaqooyin badan, iyo hawo sare, taas oo u baahan adeegsiga agabyada balaastigga ah oo leh xoog wanaagsan iyo heer-kul sarreeya.

Shirkado badan oo Shiine ah ayaa sidoo kale soo saara balaastikado gaar ah oo wax laga badalay sida PA46, PPS, PEEK, iwm, si ay sifiican ugu bixiyaan qalabka balaastigga waxqabadka sare leh ee soo saarayaasha qalabka korontada ku shaqeeya ee hooseeya. Marka loo eego isbeddelka 5G ee 2019, qaybaha anteenooyinka waxay u baahan yihiin qalab joogto ah oo sare-koronto ah, iyo walxaha joogtadoodu yar tahay ee dielectric ayaa looga baahan yahay si loo gaaro daahitaan hoose. Tani waxay leedahay shuruudo sare oo loogu talagalay balaastigga wax laga beddelay waxayna sidoo kale keenaysaa fursado cusub.
