Izinto ezinamathelayo zamathayela zibalulekile ekwakhiweni, ziqinisekisa ukuthi amathayela anamathela ngendlela efanele endaweni engaphezulu, ahlinzeka ngokuqina, futhi amelane nezimo ezihlukahlukene zemvelo. Izinamatheliso zamathayela zendabuko ngokuyinhloko zakhiwe usimende, isihlabathi, nama-polymers. Kodwa-ke, ukufakwa kwe-rubber powder kanye ne-cellulose kunikeza izithuthukisi ezingaba khona ekusebenzeni nasekusimameni kwemvelo.
Ukuqonda i-Rubber Powder neCellulose
I-Rubber Powder:
Impuphu yerabha isuselwa kunjoloba egaywe kabusha, ngokuvamile etholakala kumathayi okuphela kwempilo. Inqubo yokugaywa kabusha ihlanganisa ukuhlikihla amathayi abe yizinhlamvana ezincane, ezigaywa zibe impushana ecolekileyo. Le nto icebile ngezakhiwo ze-elastomeric, ihlinzeka ngokuguquguquka nokuqina. Ukusetshenziswa kwempushana yerabha ezintweni zokwakha akugcini nje ngokubuyisela imfucuza kodwa futhi kunikeza izici ezizuzisayo emkhiqizweni wokugcina.
I-Cellulose:
I-Cellulose, i-polymer ephilayo etholakala ezindongeni zamaseli ezitshalo, isetshenziswa ezimbonini ezahlukahlukene ngenxa yemvelo yayo ene-fibrous kanye nokuhambelana kwe-biocompatibility. Ekwakhiweni, i-cellulose ivame ukungezwa ezintweni zokuthuthukisa i-viscosity, ukugcinwa kwamanzi, namandla emishini. Ingathathwa ku-pulp yokhuni, iphepha eligaywe kabusha, noma imikhiqizo yezolimo, iyenze ibe isithasiselo esisebenza ngezindlela eziningi nesimeme.
Izinzuzo ze-Rubber Powder kanye neCellulose ku-Tile Adhesives
Ukuguquguquka Okuthuthukisiwe kanye Nokumelana Ne-Crack:
Enye yezinzuzo eziyinhloko zokwengeza i-powder yerabha kuma-adhesives we-tile ukwanda kokuguquguquka. Izinto ezinwebekayo zenjoloba zisiza ukumunca ingcindezi futhi zivimbele ukuqhekeka ngaphansi kokunwetshwa okushisayo noma ukunyakaza kwe-substrate. Lesi sici sinenzuzo ikakhulukazi ezindaweni ezingaphansi kokushintshashintsha kwezinga lokushisa noma ukudlidliza.
Ukugcina Amanzi Okuthuthukisiwe Nokusebenza:
I-Cellulose ithuthukisa amandla okugcina amanzi ezinto ezinamathelayo zamathayela, ivimbele ukomiswa ngaphambi kwesikhathi futhi ivumele ukuphulukiswa okungcono. Lokhu kubangela amandla okunamathela athuthukisiwe kanye nengxube esebenzayo, okwenza inqubo yokufaka isicelo ibe bushelelezi futhi isebenze kahle. I-hydration efanele ngesikhathi sokwelashwa ibalulekile ekuthuthukisweni kwezakhiwo ezigcwele zemishini ye-adhesive.
Ukusimama Kwemvelo:
Ukufaka i-rubber powder kanye ne-cellulose ezintweni ezinamathelayo zamathayela kukhuthaza ukusimama kwemvelo ngokuvuselela izinto ezilahlwayo kanye nokunciphisa ukuthembela ezinsizeni ezingavuseleleki. Ukusebenzisa irabha egaywe kabusha kudingidwa udaba lokulahlwa kwamasondo, okuletha izinselelo ezinkulu zemvelo. Ngokufanayo, i-cellulose evela ephepheni eligaywe kabusha noma imfucumfucu yezolimo ifaka isandla emnothweni oyindilinga, inciphisa isidingo sezinto ezingaziwa.
Ukusebenza Kwezindleko:
Izinto ezigaywe kabusha njengempushana yerabha kanye neselulosi kungaba ezinye izindlela ezingabizi kunezithasiselo zendabuko. Zivame ukuza endaweni yentengo ephansi kunama-polymers okwenziwa futhi zinganciphisa izindleko eziphelele zokubunjwa kwe-adhesive adhesive. Lokhu kusebenza kahle kwezindleko, kuhambisana nezimfanelo zokusebenza ezithuthukisiwe, kwenza lezi zinto zikhange kubakhiqizi nakubathengi ngokufanayo.
Izinselelo Nokucatshangelwa
Ukuhambisana Nokulungiswa Kokwakhiwa:
Ukuhlanganisa i-rubber powder kanye ne-cellulose ku-adhesive tile kudinga ukucatshangelwa ngokucophelela ukuhambisana nezinye izingxenye. Imvelo ye-hydrophobic ye-rubber powder ingaba nezinselele ekuzuzeni ingxube efanayo kanye nokubopha okuqinile ngezinto zikasimende. Ukulungiswa kokwakhiwa, njengokufakwa kwama-agent ahlakazayo noma ama-coupling agents, kungase kudingeke ukuze kuqinisekiswe i-homogeneity kanye nokunamathela.
Ukulinganisa Kwempahla Yemishini:
Nakuba impushana yerabha ithuthukisa ukuguquguquka, amanani eqile angehlisa amandla acindezelayo nokuqina kokunamathela. Kubalulekile ukulinganisa amanani asetshenziselwa ukugcina ubuqotho besakhiwo se-adhesive ngenkathi uzuza ekunwebeni okungeziwe. Ngokufanayo, i-cellulose kufanele yengezwe ngamanani afanele ukuze kugwenywe izingxube eziwugqinsi okungenzeka kube nzima ukuzisebenzisa.
Ukulawulwa Kwekhwalithi kanye Nokumiswa:
Ukugcina ikhwalithi engaguquki ezintweni ezigaywe kabusha kungaba inselele. Ukwehluka emthonjeni nasekucutshungulweni kwempuphu yerabha kanye neselulosi kungaholela ekuhlukeni ekusebenzeni. Ukulinganisa kanye nezinyathelo eziqinile zokulawula ikhwalithi ziyadingeka ukuze kuqinisekiswe ukuthi umkhiqizo wokugcina uhlangabezana nezicaciso zemboni kanye nemibandela yokusebenza.
Ukuqina Kwesikhathi Eside:
Ukuqina kwesikhathi eside kwezinamathelisi zamathayili aqukethe impushana yerabha kanye neselulosi kufanele kuhlolwe kahle. Izinto ezinjengokuchayeka kwe-UV, umswakama, nokumelana namakhemikhali kudlala indima ebalulekile ekuphileni isikhathi eside kokunamathelayo. Ukuhlola okubanzi ngaphansi kwezimo ezihlukahlukene kubalulekile ukuze kuqinisekiswe ukuthi ingcina eguquliwe ingakwazi ukumelana nezidingo zezinhlelo zokusebenza zomhlaba wangempela.
Izifundo Nezicelo
Izicelo Zomhlaba Wangempela:
Izifundo eziningi kanye nezinhlelo zokusebenza zomhlaba wangempela zibonise ukusebenza kwempushana yerabha kanye neselulosi ezintweni zokwakha. Isibonelo, ucwaningo luye lwabonisa ukuthi impushana yerabha ingathuthukisa ukumelana nokukhathala nokuqina kukakhonkolo. Ngokufanayo, imicu ye-cellulose isetshenziselwe ukuthuthukisa izakhiwo zemishini kanye nokusimama kwezinto ezihlukahlukene zokwakha.
Isibonelo: Izinto Ezinamathelayo Ezihlanganisiwe Zokufaka Amathayili:
Ucwaningo oluyisibonelo oluhlanganisa okunamathelayo kwamathayela ayingxube aqukethe impushana yeraba neselulosi yagqamisa izinzuzo ezimbalwa. I-adhesive eguquliwe ibonise ukuguquguquka okuthuthukisiwe, kunciphisa ubungozi bokuhlukaniswa kwamathayili ezindaweni ezinengcindezi ephezulu. Ukwengeza, izakhiwo ezithuthukisiwe zokugcina amanzi zenza kube lula ukuphulukiswa okungcono, okuholela ekunamatheleni okuqinile. Ucwaningo luphinde lwaphawula ukwehla kwezindleko zempahla kanye nomthelela omuhle kwezemvelo ngenxa yokusetshenziswa kwezingxenye ezigaywe kabusha.
Amathemba Ekusasa
Amafomula amasha:
Ucwaningo lwesikhathi esizayo kanye nemizamo yokuthuthukisa ingagxila ekwandiseni ukwakheka kwezinamathelisi zamathayili ngempuphu yerabha kanye neselulosi. Ngokuzama izilinganiso ezihlukene, osayizi bezinhlayiyana, nezindlela zokucubungula, abakhiqizi bangakha izinto zokunamathisela ezihambisana nezinhlelo zokusebenza ezithile kanye nezidingo zokusebenza.
Ukuhlola Okuthuthukile Nokulingisa:
Izindlela zokuhlola ezithuthukile namathuluzi okulingisa anganikeza imininingwane ejulile ngokuziphatha kwalezi zinamathiselo eziguquliwe ngaphansi kwezimo ezihlukahlukene. I-Finite element analysis (FEA) nezinye izindlela zokumodela zekhompyutha zingabikezela ukusebenza kwe-adhesive ngokuhamba kwesikhathi, kusize ukucolisa ukwakheka nokuqinisekisa ukuqina kwesikhathi eside.
Imikhuba Yokwakha Esimeme:
Imboni yezokwakha iya ngokuya iqhubekela phambili ezindleleni ezisimeme, futhi ukusetshenziswa kwezinto ezigaywe kabusha njengempushana yerabha kanye ne-cellulose kuhambisana nalo mkhuba. Njengoba imithetho yezemvelo iba ngokuqina, ukwamukelwa kwezinto ezingavumelani nemvelo ezakhiweni cishe kuzokwanda, kuqhubekisele phambili ukuqamba okusha nokwamukelwa kwalezi zithako kumathayela anamathelayo.
Ukufakwa kwempuphu yerabha kanye neselulosi ezintweni ezinamathelayo zamathayela kuveza indlela ethembisayo yokuthuthukisa ukusebenza nokukhuthaza ukusimama. Izinzuzo zokuguquguquka okukhulayo, ukugcinwa kwamanzi okuthuthukisiwe, kanye nokusebenza kahle kwezindleko kwenza lezi zinto zibe ezinye izindlela ezikhangayo kunezithasiselo zendabuko. Kodwa-ke, izinselele ezihlobene nokuhambisana, ukulawulwa kwekhwalithi, nokuqina kwesikhathi eside kufanele kubhekwane nakho ngokwakhiwa ngokucophelela nokuhlola okunzima. Njengoba imboni yezokwakha iqhubeka nokubeka phambili ukusimama, ukwamukelwa kwezinto ezintsha ezifana nempushana yerabha kanye neselulosi sekulungele ukukhula, okunomthelela emikhubeni yokwakha eqinile futhi evumelana nemvelo.
