Izinamathiseli kanye nezinamathiseli kuhlobene kakhulu uma kukhulunywa ngokunamathelisa noma ukubopha izingxenye ezimbili noma ngaphezulu ndawonye. Zombili ziyizinhlayiya ezinamathelayo ezicutshungulwa ngamakhemikhali ukuze kwakheke isibopho esiqinile endaweni esetshenziswa kuyo.
Izinto zokunamathisela zemvelo kanye nezinto zokunamathisela ziyatholakala eduze kwethu ekuqaleni. Zombili zisetshenziswa lapha nalaphaya, kusukela emakhaya kuya ekusungulweni kwezobuchwepheshe. Isibonelo, ukupakisha, ukukhiqizwa kwephepha, ukukhiqizwa kwezindiza, izindiza, izicathulo, amadivayisi ezimoto kanye ne-elekthronikhi konke kuyizimboni ezidinga izinto zokunamathisela kanye nezinto zokunamathisela.
Ukuqhathanisa Phakathi Kwezinto Zokunamathela Nezivala
La magama amabili afana futhi angashintshana ngisho nasezimweni ezithile, kodwa kusekhona umehluko phakathi kwawo ngenhloso nasekusetshenzisweni kokugcina. I-Adhesive uhlobo lwento esetshenziselwa ukubamba izindawo ezimbili ngendlela eqinile nehlala njalo kanti i-sealant iyinto esetshenziselwa ukunamathisela izindawo ezimbili noma ngaphezulu.
Eyokuqala iwusizo uma kudingeka inhlanganisela ehlala isikhathi eside neqinile; eyesibili isetshenziselwa ukugwema ukuvuza koketshezi noma kwegesi endaweni yokuqala ngenhloso yesikhashana. Amandla esibopho se-sealant awabuthakathaka ngokwemvelo kunawe-glue, njengoba ukusebenza kwawo kuncike ohlotsheni oluthile kanye nokusetshenziswa okuhlosiwe, kufaka phakathi amandla amelana nawo kanye nezakhiwo zawo zokushisa.
Izinamathiseli kanye nezinamathiseli zihlanganyela izici ezibalulekile zokuziphatha ezivumela ukubopha okuphumelelayo:
-
Ukugeleza kwamanzi: Kokubili kumele kubonise ukuziphatha okufana noketshezi ngesikhathi sokufaka ukuqinisekisa ukuthintana okufanele nezindawo noma izinhlaka, kugcwalise ngempumelelo noma yiziphi izikhala.
-
Ukuqina: Zombili ziyaqina zibe yisimo esiqinile noma esiqinile kancane ukuze zisekele futhi zimelane nemithwalo ehlukahlukene esetshenziswa esibophweni.
Ukuqaqamba Kwezinto Zokunamathela Nezivala
Izinamathiseli zihlukaniswe ngezinamathiseli zemvelo kanye nezinamathiseli zokwenziwa ngokwemvelaphi yazo. Ukuqina kuthathwa njengokumelana noketshezi noma ukugeleza. Izinamathiseli eziqinile kanye nezisivikelo kuyizinto ezingezona ezeNewtonian. Ngamanye amazwi, ukufundwa kwe-viscosity kuncike esilinganisweni sokusika esilinganisiwe.
Ukuqina kudlala indima ebalulekile ekukhiqizweni nasekusetshenzisweni kwezinamathelisi, okusebenza njengesibonakaliso esibalulekile sezakhiwo ezifana nobuningi, ukuzinza, okuqukethwe kwe-solvent, izinga lokuxuba, isisindo sama-molecule, kanye nokuvumelana okuphelele noma ukusatshalaliswa kosayizi wezinhlayiya.
Ukuqina kwe-glue kuyahlukahluka kakhulu ngokusekelwe ekusetshenzisweni kwayo okuhlosiwe, njengokuvala noma ukubopha. I-glue ihlukaniswe ngezinhlobo ze-glue eziphansi, eziphakathi nendawo, kanye nezinhlobo ze-glue ephezulu, ngayinye ifanele izimo ezithile zokusetshenziswa:
-
Izinamathiseli Eziphansi Zokunamathela: Ilungele ukufakwa emabhodweni, ukufakwa emabhodweni, kanye nokufuthwa ngenxa yekhono lazo lokugeleza kalula nokugcwalisa izikhala ezincane.
-
Izinamathiseli Eziphakathi Zokunamathela: Ivame ukusetshenziswa ekuhlanganiseni nasekuvaleni, okunikeza ibhalansi yokugeleza nokulawula.
-
Izinamathiseli Ezinobukhulu Obukhulu: Yenzelwe izinhlelo zokusebenza ezingaconsi noma ezinganciphisi, njenge-epoxies ethile, lapho ubuqotho besakhiwo bubalulekile khona.
Izindlela zokulinganisa i-viscosity zendabuko zincike ekuthathweni kwesampula ngesandla kanye nokuhlaziywa kwelebhu, okuthatha isikhathi futhi kudinga umsebenzi omningi. Lezi zindlela azifaneleki ukulawula inqubo ngesikhathi sangempela, njengoba izakhiwo ezilinganiswe elebhu zingase zingabonisi ngokunembile ukuziphatha kwe-glue emgqeni wokukhiqiza ngenxa yezici ezifana nesikhathi esidlulile, ukuchitheka, noma ukuguga koketshezi.
I-Lonnmeterimitha ye-viscosity eqondileinikeza ikhambi elisezingeni eliphezulu lokulawula i-viscosity ngesikhathi sangempela, ibhekana nemikhawulo yezindlela zendabuko kanye nokuthuthukisa izinqubo zokukhiqiza i-glue. Ihlangabezana nalokhu kuhlukahluka ngebanga elibanzi lokulinganisa (0.5 cP kuya ku-50,000 cP) kanye nezimo zezinzwa ezingenziwa ngokwezifiso, okwenza ihambisane nezinhlobo ezahlukene ze-glue, kusukela kuma-cyanoacrylates ane-viscosity ephansi kuya kuma-resin epoxy ane-viscosity ephezulu. Amandla ayo okuhlanganisa amapayipi, amathangi, noma ama-reactor anezinketho zokufaka eziguquguqukayo (isb., i-DN100 flange, ukujula kokufaka kusuka ku-500mm kuya ku-4000mm) kuqinisekisa ukuguquguquka kuzo zonke izinhlobo zokukhiqiza ezahlukene.
Ukubaluleka Kokuqapha Ukujiya Nobuningi
Ukukhiqizwa kokunamathela kuhilela ukuxuba noma ukusabalalisa izinto ezahlukahlukene ukuze kufezwe izakhiwo ezithile, okuhlanganisa ukumelana namakhemikhali, ukuzinza kokushisa, ukumelana nokushaqeka, ukulawula ukushwabana, ukuguquguquka, ukusebenza kahle, kanye namandla emkhiqizweni wokugcina.
I-Lonnmeter inline viscometer yenzelwe ukusetshenziswa okuhlukahlukene ezindaweni ezahlukene zokulinganisa izinamathiseli, izinamathiseli, noma izinqubo zokukhiqiza isitashi. Ivumela ukuqapha inline kwe-viscosity kanye nemingcele ye-derivative efana nobuningi kanye nokushisa. Ukufakwa kungaba ngqo ethangini lokuxuba ukuqonda ukuvela kwe-viscosity nokunquma ukuthi ukuxuba okudingekayo kufinyelelwa nini; emathangini okugcina ukuqinisekisa ukuthi izakhiwo zoketshezi ziyagcinwa; noma emapayipini, njengoba uketshezi lugeleza phakathi kwamayunithi.
Ukufakwa Kwamamitha Okugoba Nokujiya Okungaphakathi
Emathangini
Ukulinganisa i-viscosity ngaphakathi kwethangi lokuxuba uketshezi olunamathelayo kwenza kube lula ukulungisa ngokushesha ukuqinisekisa izakhiwo zoketshezi ezihambisanayo, okuholela ekwandeni kokusebenza kahle kokukhiqiza kanye nokunciphisa imfucuza yezinsiza.
Imitha yokulinganisa ubukhulu ingafakwa ethangini lokuxuba. Amamitha okulinganisa ubukhulu kanye nokulinganisa ubukhulu awanconywa ukufakwa ngqo emathangini okuxuba, njengoba isenzo sokuxuba singaletha umsindo othinta ukunemba kokulinganisa. Kodwa-ke, uma ithangi lifaka umugqa wephampu yokujikeleza kabusha, imitha yokulinganisa ubukhulu kanye nokulinganisa ubukhulu ingafakwa ngempumelelo epayipini, njengoba kuchaziwe esigabeni esilandelayo.
Ukuze uthole isiqondiso sokufakwa esiklanyelwe wena, amaklayenti kufanele axhumane nethimba lokusekela futhi anikeze imidwebo noma izithombe zamathangi, echaza amachweba atholakalayo nezimo zokusebenza ezifana nokushisa, ingcindezi, kanye nokuthambekela okulindelekile.
Kumapayipi
Indawo efanele yokufaka amamitha e-viscosity kanye ne-density kumapayipi e-adhesive fluid isendaweni engqiniba, kusetshenziswa i-axial setup lapho i-probe sensing element ibhekene nokugeleza koketshezi. Lokhu ngokuvamile kudinga i-probe ende yokufaka, engenziwa ngokwezifiso ubude bokufaka kanye nokuxhumeka kwenqubo ngokusekelwe kusayizi wepayipi kanye nezidingo zalo.
Ubude bokufakwa kufanele buqinisekise ukuthi into yokuzwa ithintana ngokuphelele noketshezi olugelezayo, kugwenywe izindawo ezifile noma ezimile eduze kwembobo yokufaka. Ukubeka into yokuzwa engxenyeni yepayipi eqondile kusiza ukuyigcina ihlanzekile, njengoba uketshezi lugeleza phezu komklamo we-probe ohlelekile, okuthuthukisa ukunemba kokulinganisa nokuthembeka.
