Ngokufunda isiphumo semithombo eyahlukeneyo ye-hydropylcelcelculose (HPMC) kushicilelo, iipropathi ze-HPMC kunye ne-HPMC yoHlelo lwe-3D, kwaye indlela yayo ye-HPMC yahlaziywa i-microsphology. Iziphumo zibonisa ukuba udaka lodaka luyancipha ngokunyuka komxholo we-HPMC, oko kukuphucula ukunyuka komxholo we-HPMC, kodwa i-fluidity yobuxoki iphucuka. Ukuphuculwa; Iqondo lokugcina imilo kunye nokunganyangeki kwe-Peneting phantsi kokuziswa kwesisindo ngenxa yokunyuka komxholo we-HPMC, oko kukuthi, ukunyuka komxholo we-HPMC, ixesha lokushicilela lililo ixesha elide; Ukusuka kwindawo yokujonga i-raduelogy, kunye nokwanda komxholo we-HPMC, i-vialfield kunye noxinzelelo lweplastiki kunye noVekyuli weplastiki olwanda kakhulu, kwaye ukubetheka kuphuculwe; I-ThtriiXoppy yonyuke yanda kwaye yancipha ngokunyuka komxholo we-HPMC, kunye noshicilelo oluphuculweyo; Umxholo we-HPMC wanda kakhulu kuya kubangela ukuba isidlo senziwe kunye namandla kucetyiswa ukuba umxholo we-HPMC akufuneki ungadli i-0.20%.
Kwiminyaka yakutshanje, ukuprinta i-3D (okwaziwa ngokuba nemveliso yothungelwano ") ikhutshiwe ngokukhawuleza kwaye isetyenziswe ngokubanzi kwimimandla emininzi efana ne-bioengine, i-aerospace, nendalo yobugcisa. Inkqubo yasimahla yokuprinta ye-3D iphucule kakhulu impahla kunye nokuguquguquka koyilo lwesakhiwo kunye nendlela eyakhiwe ngokuzenzekelayo ayigcinile kakhulu, kodwa ilungele iiprojekthi zokwakha kwiindawo ezahlukeneyo ezinzima. Ukudityaniswa kwetekhnoloji yokuprinta i-3D kunye nendawo yokwakha inobuchule kwaye iyathembisa. Okwangoku, izinto ezisekwe kwisamente 3D Inkqubo yokuBhengeza yenkqubo yokukhutshelwa kwenkqubo ye-contour (kubandakanya inkqubo ye-contour ye-comtour) kunye nenkqubo yokushicilela yekhonkrithi (inkqubo ye-D-Suppler). Phakathi kwazo, inkqubo yokuphosaka i-staction ineengenelo zomehluko omncinci kwiNkqubo yeNgcebiso yeNgqongo yeSintu, ukuba inokwenzeka kumacandelo amakhulu obuninzi kunye neendleko zokwakha. Inzuzo engaphantsi iyona iye yaba zii-hotspots zangoku zophando zetekhnoloji ye-3D yokuprinta zesamente esekwe.
Ngezinto ezisisiseko zesamente ezisetyenziswa njenge "zi-IK" zokuprintwa kwe-3D, iimfuno zabo zentsebenzo zahlukile kwezixhobo ezixubeneyo ezixubileyo, kwaye kukho izinto ezithile, kwaye kunjalo, ayizukuwa phantsi kwesenzo sobunzima bayo kunye uxinzelelo lomaleko ophezulu. Ukongeza, inkqubo yokuprinta ye-3D yenza iindawo eziphakathi kweendawo ukuze kuqinisekiswe iipropathi zoomatshini abalungileyo bommandla we-interlather, izinto zokwakha ze-3D kufuneka zibe ne-adhesion elungileyo. Isishwankathelo, uyilo lokwahlulwa, ukuqiqa, kunye nokunamathela okuphezulu kwenziwe ngaxeshanye. Izixhobo ezisekwe kwimo yesamente zezinye zeemfuneko zokusetyenziswa kwetekhnoloji ye-3D kwicandelo lolwakhiwo. Ukulungelelanisa inkqubo ye-hydration kunye neepropathi ze-riheological zezinto ezinzima zesamente ziindlela ezimbini ezibalulekileyo zokuphucula ukusebenza ngentla. Uhlengahlengiso lwenkqubo ye-hydration yezinto eziluncedo kunzima ukuzisebenzisa, kwaye kulula ukubangela iingxaki ezinje ngombhobho wokubhuka; Kwaye ukumiselwa kweepropathi ze-rithological kufuneka kugcinwe ulwelo ngexesha lenkqubo yokuprinta kunye nokwakhiwa kwesantya emva kokupheliswa kwezinto, i-viscosity, i-viscosity, njl.
I-HydroxyPOpyl Methylcelcelsulose (HPMC) yi-polymer eqhelekileyo. I-hydroxyl kunye ne-ether Bonds kwi-molecular thein inokudityaniswa ngamanzi asimahla nge-hydrogen. Ukwazisa ngekhonkrithi kunokuphucula ngokufanelekileyo ubumbano bayo. nokugcinwa kwamanzi. Okwangoku, uphando ngeziphumo ze-HPMC kwipropathi yezixhobo ezisekwe kwizinto ezenziweyo kulwelo, ukugcinwa kwamanzi, kunye ne-geology, kunye nokwahlula-hlulwa, ukubekwa, njl. Ukongeza, ngenxa yokunqongophala kwemigangatho efanayo yokuprintwa kwe-3D, indlela yovavanyo yokuprinta izinto ezisekwe kwizinto ezenziweyo ayikasungulwanga. Ukuqhekeka kwezixhobo kuvavanywa linani lamacala aprintiweyo eqhiphuke ishwangusha okanye ukuphakama okuphezulu. Ezi ndlela zovavanyo ezingentla ziphantsi komanyano oluphezulu, indalo iphela, kunye nenkqubo ye-cumberberbeme. Indlela yovavanyo lwentsebenzo inezinto ezininzi ezinokubakho kunye nexabiso kwisicelo sobunjineli.
Kweli phepha, imida eyahlukeneyo ye-HPMC yaziswa kwizinto ezisekwe kwimo yesamente yokuphucula ubuprinta, kwaye imiphumo ye-HPMC ivavanywa ngokufanelekileyo ngokufundwayo ngokufundisisa, iipropathi ze-RTEMIL kunye neepropathi zoomatshini. Ngokusekwe kwiipropathi ezinje ngolwenzi ngokusekwe kwiziphumo zovavanyo, udaka oluxutyungelwe nge-HPMC yekhuselo, kwaye imibutho efanelekileyo yequmrhu elishicilelweyo lavavanywa; Ngokusekwe kuphononongo lwe-morphology ye-microscopic yesampulu, indlela yangaphakathi yentsebenzo yentsebenzo yendalo yayiphononongwa. Kwangelo xesha, izinto ezisekwe kwi-3D zesamente yasekwa. Indlela yovavanyo olubanzi lwentsebenzo eprintisiweyo ukwenzela ukukhuthaza ukusetyenziswa kwetekhnoloji ye-3D kwicandelo lolwakhiwo.
