iindaba

Njengoko sijongene nengxaki enkulu yongcoliseko lokusingqongileyo, ulwazi ngokhuseleko lokusingqongileyo luye lwanda kancinci kancinci, kwaye umkhwa wokusebenzisa izixhobo zendalo nawo uye wakhula. Ukusetyenziswa kwamandla aphantsi kunye neempawu ezivuselelekayo zemicu yezityalo kuye kwatsala ingqalelo enkulu. Kuya kugqitywa kwixesha elizayo. Kuya kubakho uphuhliso oluphezulu. Nangona kunjalo, imicu yezityalo zizinto ezahlukeneyo ezinobume kunye nesakhiwo esintsonkothileyo, kwaye umphezulu wayo uqulethe amaqela e-hydroxyl aphilic. Ubudlelwane kunye ne-matrix bufuna unyango olukhethekileyo ukuphucula iipropati zemicu edityanisiweyo. Imicu yezityalo isetyenziselwa izinto ezidityanisiweyo, kodwa uninzi lwazo lukhawulelwe kwimicu emifutshane kunye nemicu engaqhubekiyo. Iipropati zokuqala ezintle azikasetyenziswa ngokupheleleyo, kwaye zisetyenziswa kuphela njengezizalisi. Ukuba singazisa itekhnoloji yokuluka, sisisombululo esilungileyo. Ii-preforms ezilukiweyo zemicu yezityalo zinokubonelela ngeendlela ezininzi zokusebenza kwizixhobo ezidityanisiweyo, kodwa okwangoku zisetyenziswa kancinci kwaye zifanelekile uphando olongezelelweyo kunye nophuhliso. Ukuba singacinga ngokutsha ngendlela yendabuko yokusebenzisa ifayibha, size singenise iingcamango zobuchwepheshe obudibeneyo bale mihla ukuze siyiphucule, siphucule iingenelo zokusetyenziswa kwayo kwaye siphucule ukusilela kwayo, iya kukwazi ukunika ifayibha yezityalo ixabiso elitsha kunye nokusetyenziswa kwayo.

Ifayibha yezityalo ibisoloko ingasahlukaniswa nobomi bomntu bemihla ngemihla. Ngenxa yeempawu zayo ezilula nezivuselelekayo, ifayibha yezityalo iye yaba yinto ebalulekileyo ebomini bomntu. Nangona kunjalo, ngokuqhubela phambili kwetekhnoloji kunye nokunyuka kweshishini le-petrochemical, iifayibha ezenziwe ngabantu kunye neeplastiki ziye zathatha indawo yeefayibha zezityalo kancinci kancinci njengezinto eziphambili ngenxa yeenzuzo zobuchwepheshe bemveliso obuphuhlisiweyo kakhulu, ukwahlukahluka kwemveliso kunye nokuqina okuhle. Nangona kunjalo, i-petroleum ayisiyonto ivuselelekayo, kwaye iingxaki zokulahla inkunkuma ezibangelwa kukulahlwa kweemveliso ezinjalo kunye nokukhutshwa okukhulu kongcoliseko ngexesha lenkqubo yokuvelisa zibangele ukuba abantu bacinge ngokutsha ngokusetyenziswa kwezixhobo. Phantsi kwendlela yokukhusela okusingqongileyo kunye nokuzinza, iifayibha zezityalo zendalo ziye zafumana ingqalelo. Kwiminyaka yakutshanje, izinto ezidityanisiweyo ezisebenzisa iifayibha zezityalo njengezinto zokuqinisa ziye zaqala ukufumana ingqalelo.

Ifayibha yezityalo kunye ne-composite

Isakhiwo esidityanisiweyo sinokuyilwa yinkqubo yokuvelisa. Ifayibha egqunywe nge-matrix inika imo epheleleyo necacileyo yento, kwaye ikhusela ifayibha ekuwohlokeni ngenxa yempembelelo yokusingqongileyo, kwaye isebenza njengebhulorho yokudlulisa uxinzelelo phakathi kweefayibha; ngelixa ifayibha ithwala uninzi lwamandla angaphandle kunye neempawu zayo ezintle zoomatshini kwaye ingadlula. Ulungiselelo oluthile lufezekisa imisebenzi eyahlukeneyo. Ngenxa yoxinano lwayo oluphantsi kunye namandla aphezulu, ifayibha yezityalo inokuphucula iimpawu zoomatshini kwaye igcine uxinano oluphantsi xa yenziwe ibe zii-FRP composites. Ukongeza, iifayibha zezityalo ikakhulu zii-plant cell aggregates, kwaye imingxuma kunye nezikhewu ezikuyo zinokuzisa iipropati ezintle zokuthintela ubushushu kwizinto. Xa kujongwe amandla angaphandle (njengokungcangcazela), ikwazuza kwi-porosity yayo, evumela amandla ukuba aphele ngokukhawuleza. Ngaphezu koko, inkqubo epheleleyo yokuvelisa ifayibha yezityalo ikhupha ungcoliseko oluncinci kwaye isebenzisa iikhemikhali ezincinci, inobushushu obuphantsi bokusebenza, inenzuzo yokusetyenziswa kwamandla aphantsi, kwaye inqanaba lokuguguleka koomatshini ngexesha lokucubungula nalo liphantsi; ukongeza, ifayibha yezityalo yimpawu zendalo eziVuselelekayo, imveliso ezinzileyo inokufezekiswa phantsi kolawulo olufanelekileyo kunye nolawulo. Ngoncedo lwetekhnoloji yanamhlanje, ukubola kunye nokumelana nemozulu kwezinto kuye kwalawulwa kakuhle, ukuze zibole emva komjikelo wobomi bemveliso, ngaphandle kokubangela ukuqokelelwa kwenkunkuma, kwaye ikhabhoni ekhutshwa kukubola nayo ifumaneka ekukhuleni kokuqala. Umthombo wekhabhoni emoyeni unokuba yikhabhoni engathathi cala.
