Ukungcoliswa Kwesikhunta, Itshe Lezinso Lomhlaba WePlastiki
Isikhathi sokufunda esilinganisiwe: imizuzu emi-4, imizuzwana emi-4
Uma umuntu enokudla okungavamile, ukuqoqwa kwe-calcium oxalate ngenxa yamaprotheni amaningi, noma ukunqwabelana kwemikhiqizo engcolile ngenxa yamafutha amaningi noshukela, noma ukufakwa kukasawoti womchamo ngenxa yokuphila kokunganyakazi, kungabangela ukwakheka kwezixuku zamatshe.Futhi ukungcoliswa kwesikhunta imvula encane evela epulasitiki encibilikisiwe futhi ngemva kokuqoqwa kwesikhathi, endaweni yesikhunta ekhiqizwa ukunamathela.Uma indawo yokubumba isinamathisele isikali sesikhunta, ukunqwabelana kwesikali sesikhunta kuzoshesha futhi kusheshe.
Ukungcola kwesikhunta endaweni yesikhunta
Amatshe ukuqoqwa kwe-calcium oxalate kanye neminye imikhiqizo yemfucuza evela ekudleni okudliwe;ama-mold deposits ayizithasiselo ze-molecule ezincane ezifana ne-flame retardants kanye nezinto zokugcoba, futhi zingase zibe ama-oligomers abangelwa ukuwohloka kokushisa.Ngaphambi kokuba "itshe", isikali sesikhunta singase sibe ukuvuthwa kwegesi okungaphazamisi ukukhiqiza uma kukhishwe ngesikhathi.Njengosawoti we-calcium oxalate womchamo ngaphambi kwetshe, akukho monakalo ekuphuzeni amanzi amaningi nokuwakhipha ngesikhathi.Ukungcoliswa kwesikhunta kufana nendlela kanye nenqubo yokwakhiwa kabusha kwamatshe.Ukungcoliswa kwesikhunta kungase kuvimbe umgudu wokukhipha umoya, kubangele ukuthi imikhiqizo yepulasitiki ihanguke, ingase futhi inamathele emkhiqizo ibe nomthelela ekubukekeni, njengoba ukungcola komzimba wangaphandle kungase kuthinte izakhiwo zikagesi zomkhiqizo.Imboni yokucubungula bekufanele ihlanze isikhunta ngenkathi ikhiqiza, futhi kungenzeka ukuthi imikhiqizo enesici iphume lapho bebengazi ngakho ekuqaleni.
Izibunjwa kufanele zisulwe ngedayimane lokugaya njalo ngamahora ambalwa
Lesi sihloko sizokhuluma ngezimbangela ze-mold deposits ezivela ezicini ezintathu eziyinhloko: impahla, inqubo kanye nesikhunta.Lesi sihloko sizokhuluma ngezimbangela ze-mold deposits ezivela ezicini ezintathu eziyinhloko: impahla, inqubo kanye nesikhunta.
1Okubalulekile
Okubalulekile kuvame ukuba yisizathu esiyinhloko sokuvela kokukhubazeka kwesikali sesikhunta.Ngokuvamile kuhlaziywa kusuka kule mibono emithathu elandelayo.
Esokuqala yi-ukubola kwe-resin yepulasitiki.I-resin endaweni engaphezulu kwezinga lokushisa layo lokubola ukuze ikhiqize ama-oligomers, ukubola okuningi kuzobambelela ekwakhiweni kokungaphezulu, okubonwa kakhulu umehluko wokushisa oncibilikayo phakathi kwemikhiqizo ye-alloy.Okuqukethwe okusele kwe-monomer kwama-resin ahlukene ngokwawo nakho kunomthelela.
Okwesibili yi-ukwehla kwezithako ze-molecule ezincane.Amapulasitiki aguquliwe azokwengezwa ekwakhiweni kwezithasiselo ezahlukahlukene ukuze anikeze okubalulekile ukusebenza noma umsebenzi ofanele, imvula endaweni enamafutha ngokuvamile iyisici sezithasiselo, ngakho-ke kulula ukuba yisikhunta esinamatheliswa kuso ngesikhathi sokubunjwa.
Owesithathu uthiumthelela wezingulube.Amapulasitiki obunjiniyela be-Thermoplastic ku-pigment encibilika emazingeni okushisa aphezulu, azonciphisa ukuzinza okushisayo kwezinto ezibunjwayo, okuholela ekulimazeni kwe-polymer kanye nokubola kwenhlanganisela ye-pigment ukuze kwakheke isikhunta.
2Inqubo yokubumba
Ama-molecule amancane ezithasiselo, imikhiqizo yokubola kwe-resin kanye namanye ama-oligomers, ekushiseni okuphezulu kuqala ngendlela ye-gasification noma i-liquefaction, ukuthintana nesikhunta kwakupholile futhi kuhlanganiswe nesikhunta, lapho izinga lokushisa liphansi lesikhunta, ukungcoliswa kwesikhunta kunamathiselwe. .
Amazinga ahlukene okukhiqizwa kwesikali sesikhunta emazingeni okushisa aphezulu naphansi esikhunta
Ukunciphisa ijubane lomjovo endaweni ethile yomkhiqizo nakho kungandisa isikhathi sokuvela kwediphozithi yesikhunta.Uma isivinini somjovo sishesha kakhulu esigabeni sokukhipha umoya, igesi ye-oligomer ngeke ibe nesikhathi esanele sokuphuma emgodini wesikhunta;uma isivinini somjovo sishesha kakhulu odongeni oluncane noma indawo ekhoneni, kuzokwenza kalula ukuthi izinga lokugunda langempela lidlule izinga lokugcina lokugunda lempahla.
3I-Mold Design Nokugcinwa
Ngeukubumba komgijimi oshisayo kanye nezinto ezingavuthiwe ezizwela ukushisa, isikhathi sokuhlala esincibilikisiwe sizoba side, ngaleyo ndlela kwandise ingozi yokungcoliswa kwesikhunta ngenxa yokubola kwempahla eluhlaza.Ngakho-ke, isikulufu somshini wokubumba umjovo sidinga ukuhlanzwa.
Ukukhipha isikhunta, uma isistimu yokukhipha umoya iklanywe kahle ngokwanele ukuze isuse ama-oligomers ahwamukile noma afakwe uketshezi esikhunjeni ngesikhathi esifanele ngaphambi kokuba isikhunta sijiye, into yokubumba isikhunta nayo izoba buthakathaka.
Ukwakha izinto ezibucayi ze-shear,izinto ezinjalo ngokuvamile zisebenzisa usayizi abagijimi emikhulu kanye namasango, multi-point gating kunganciphisa ukugeleza ibanga, isivinini umjovo ongaphakeme futhi kunciphise nengozi ukwakheka fouling isikhunta.
I-Mold deposits kulula ukuyisusa ezigabeni zokuqala zokubunjwa, ngakho-ke imigodi yesikhunta kanye nemigudu yokukhipha umoya kufanele ihlanzwe futhi igcinwe njalo, isibonelo ngemva kokwenziwa kwe-oda ngalinye.Uma isikhunta singanakekelwa futhi siseviswa isikhathi eside, kuzoba nzima kakhulu ukususa izingqimba eziwugqinsi zesikali sesikhunta leso.
Izingubo ezingezona izinduku, izigqoko ezikhethekile ezingezona izinti (isb. I-PVD coatings) endaweni yomgodi ingavimbela ukwakheka kokubola kwesikhunta futhi kufanele ihlolwe ukuze kuhlolwe ukuphumelela kokunamathela.Ukwelashwa kwe-Titanium nitride endaweni engaphakathi yesikhunta kungavimbela ukwakheka kokubola kwesikhunta esibunjeni.
Ukubumba komjovo kusetshenziswa kabanzi ezimbonini ezahlukahlukene futhi kungafinyelela ukukhiqizwa kwezingxenye ezingenamthungo, ukunemba kwezingxenye ngesikhathi esifushane.I-PorLean Tech inikezela ngezinsizakalo zokubumba umjovo zenqwaba yezinto, kufaka phakathi amapulasitiki nama-elastomer.Vele ulayishe imodeli yakhofuthi uthole ukucaphuna kwamahhala okusheshayo nezeluleko kumasevisi ahlobene.
