Ukuhlonza ikhwalithi ye-polymer powder (RDP) ebaluleke kakhulu ekwakheni izinto zokwakha nezinye izinhlelo zokusebenza. I-RDP esezingeni eliphakeme ingathuthukisa amandla webhondi, ukuguquguquka, ukumelana nokuqhekeka nokumelana kwamanzi kwezinto zokwakha, ngenkathi i-RDP ephansi ingaholela ekunciphiseni kokusebenza noma ukwehluleka. Okulandelayo umhlahlandlela onemininingwane wokuhlola ikhwalithi ye-RDP.
1. Ukwakheka kwamakhemikhali kanye ne-substrate
Izithako eziphambili: I-RDP imvamisa yenziwa ngama-polymers anjenge-ethylene vinyl acetate (EVA), i-acrylics, i-styrere buthadiene copolymer (SBR). I-RDP esezingeni eliphakeme kufanele ibe nesilinganiso esicacile nesifanele se-polymer, esithinta ngqo izici zomkhiqizo, njengamandla ebhondi, ukuguquguquka nokumelana kwamanzi.
Ukuvumelana okuphansi: I-RDP esezingeni eliphakeme kufanele ibe nokuhambisana okuhle ngezigatshana ezahlukahlukene ezinjengokusimende kanye ne-gypsum ukugwema ukuphendula okuphikisayo noma ukulahleka kokusebenza.
2. Izakhiwo ezibonakalayo
Ukubukeka: I-RDP esezingeni eliphakeme imvamisa i-powder emhlophe noma ekhanyayo enezinhlayiyana ezifanayo futhi akukho okusobala okusobala noma ukuguquguquka. Imikhiqizo ephansi ingahle ibe nezinhlayiya ngemibala engalingani noma engahambisani, ekhombisa ukuthi inqubo yokukhiqiza ayilawulwa ngokuphelele.
Ukusatshalaliswa kosayizi wezinhlayiyana: Ukusatshalaliswa kosayizi wezinhlayiyana we-RDP kuthinta okubuyiselwe kwayo. Ubukhulu bezinhlayiyana kufanele bube phakathi kobubanzi obuthile. Ubukhulu obukhulu kakhulu noma obuncane kakhulu bungathinta umphumela wokuhlakazwa kanye nokusebenza kokugcina. Ubukhulu bezinhlayiyana buvame ukukalwa ngu-Laser Partic Particle Music Analyzer.
Ubuningi be-Bulk: Ubuningi obuningi be-RDP bungenye inkomba ebalulekile, ethinta ubungako bevolumu nokusebenza kohlelo lokusebenza lwento. Ubuningi obuningi be-RDP esezingeni eliphakeme kufanele babe ngaphakathi kobubanzi obucacisiwe ukuze baqinisekise ukuthi akulula ukukhiqiza i-Flow Powder noma izinkinga zokudonsela phansi lapho zisetshenziswa.
3. Ukuhlenga kabusha
Ukuhlolwa okuvuselelayo Ngesikhathi sokuhlolwa, engeza i-RDP emanzini bese ubheka ukuhanjiswa kwayo ngemuva kokuvusa. Ukubuyiselwa okuhle kukhombisa ukuthi i-RDP inezakhiwo ezinhle ze-emulsication.
Ukuguqulwa kweViscosity: Ukuguqulwa kwe-viscosity ngemuva kokubuyiselwa kwemali emanzini nakho kuyinkomba ebalulekile yokulinganisa ukuphindisela. I-RDP esezingeni eliphakeme kufanele ihlele i-colloid ezinzile ngemuva kokuphindaphinda, futhi ushintsho lokushintsha kwento akufanele lube lukhulu kakhulu ukuqinisekisa ukusebenza kwalo kokwakha.
4. Amandla eBond
Ukuhlolwa kwamandla kwe-Tensile ne-Shear: Enye yemisebenzi esemqoka ye-RDP ukuthuthukisa amandla amabhondi. Ukusebenza kweBonding ye-RDP kungahlaziywa ngovivinyo lwamandla we-Tensile ne-Shear. I-RDP esezingeni eliphakeme kufanele ithuthukise kakhulu amandla e-monsi angodaka noma ezinye izinto.
Ukusebenza kwe-Anti-Peleng: Ngemuva kokuthi i-RDP ingezwe, ukusebenza kwe-anti-peere's peeresing kufanele futhi kwathuthukiswa kakhulu. Ukuhlolwa kokusebenza kwe-anti-peresing kuvame ukuhlolwa ngokukala amandla okubalwa.
5. Ukuvumelana nezimo
Ukuhlolwa kwe-Ductility: I-RDP esezingeni eliphakeme kufanele ikhuphule ukuguquguquka kwezinto ezibonakalayo, ikakhulukazi ku-nsiza-ungqimba lwesimende noma udaka. Ngokuhlolwa kwe-decticity, umthamo wezinhlangu wezinto ezibonakalayo ngaphansi kwezimo zokuwohloka ungalinganiswa.
Ukumelana nokuqhekeka: Ukuzivumelanisa nezimo kuthinta ngqo ukumelana nokuqhekeka kwezinto ezibonakalayo. Ngokusebenzisa ukushesha okusheshayo noma ukuhlolwa kokumelana nokuqhekeka ngaphansi kwezimo zangempela, kungahlaziywa ukuthi ukuguquguquka kwe-RDP kuhlangabezana nezidingo.
I-6. Ukumelana namanzi kanye nokuphikiswa kwe-alkali
Ukuhlolwa kokumelana kwamanzi: I-RDP kufanele ithuthukise ukumelana kwamanzi okuqukethwe. Ngokuhlola ukucwiliswa noma ukuhlolwa kokucwiliswa kwamanzi isikhathi eside, gcina ukuguqulwa kokuphikiswa kwamanzi okuqukethwe. I-RDP esezingeni eliphakeme kufanele ikwazi ukugcina ukuqina kwesakhiwo kanye namandla abusayo ngezinto ezibonakalayo.
Ukuhlolwa kwe-Alkali Ukumelana: Njengoba izinto zokwenza ukhula zivame ukuvezwa ezindaweni ze-alkaline, ukuhlolwa kokumelana ne-alkali kwe-RDP nakho kubalulekile. I-RDP esezingeni eliphakeme kufanele ilondoloze ukusebenza okuzinzile endaweni ye-alkaline futhi ngeke yehluleke ngenxa yokugqwala kwe-alkaline.
7. Ukusebenza Kwezokwakha
Isikhathi Sokusebenza: Isikhathi esisebenzayo sokusebenza kufanele sinwetshwe ngokufanele ngemuva kokuthi i-RDP ingezwe. Ukuhlolwa kwesikhathi sokusebenza kungasiza ukuqonda ukusebenza kwe-RDP ekwakhiweni kwangempela.
Ukusebenza: I-RDP ephezulu kakhulu kufanele ithuthukise ukusebenziseka kwezinto ezifana nodaka, okwenza kube lula ukuzisebenzisa nangezinga ngesikhathi sokwakha.
8. Imvelo nokuphepha
Okuqukethwe kwe-Voc: Okuqukethwe okuphansi kwe-organic compact compact (VOC) kucatshangelwa okubalulekile lapho kuhlaziya ikhwalithi ye-RDP. I-RDP esezingeni eliphakeme kufanele ihlangabezane namazinga wemvelo ukuqinisekisa ubungozi emzimbeni womuntu kanye nemvelo.
Izithako ezingenangozi: Ngaphezu kwe-VOC ephansi, i-RDP esezingeni eliphakeme kufanele futhi igweme ukusetshenziswa kwamakhemikhali ayingozi, njengezinsimbi ezisindayo noma ezinye izengezo ezinobuthi.
9. Ukukhiqizwa kanye Nezimo Zokugcina
Inqubo Yokukhiqiza: I-RDP ephezulu yekhwalithi ivame ukwamukela izinqubo zokukhiqiza ezithuthukile, njengokuchomisa isifutho, ukuqinisekisa ukuguquguquka komkhiqizo nokuqina.
Ukuqina kwesitoreji: I-RDP ephezulu yekhwalithi kufanele ibe nokuqina kwesitoreji okuhle futhi akulula ukudonsa umswakama, ukuwohloka noma ukuphazamiseka ngaphansi kwezimo ezichaziwe zokugcina.
10. Izindinganiso kanye nezitifiketi
Ukuhambisana namazinga: I-RDP esezingeni eliphakeme kufanele ihambisane namazinga afanele noma kazwelonke noma kazwelonke, njenge-ISO, ASTM noma i-EN EN CRESS. Lezi zindinganiso zihlinzeka ngemithetho enemininingwane kwizinkomba zokusebenza, izindlela zokuhlola, njll. I-RDP.
Imibiko Yesitifiketi Nezivivinyo: Abahlinzeki abanokwethenjelwa bavame ukuhlinzeka ngemibiko yokuhlolwa komkhiqizo kanye nezitifiketi, njengesitifiketi sohlelo lokuphathwa kwekhwalithi (ISO 9001) noma isitifiketi semvelo (ISO 14001), esingaqinisekisa ikhwalithi nokuphepha kwemikhiqizo.
Ukuhlonza ikhwalithi ye-latex ye-latex evuselelayo idinga ukuhlolwa okuphelele, kusuka ekuhlolweni kwamakhemikhali, impahla ebonakalayo, ukuncipha kwamandla, ukuguquguquka kwamanzi, ukuphepha kwezemvelo, ukuphepha kwezemvelo ekukhiqizweni nasezitimeleni. Lezi zinto ndawonye zinqume ukusebenza kokugcina kanye nomphumela wohlelo lokusebenza lwe-RDP. Ekuthengeni kwangempela kanye nesicelo, lezi zinto kufanele zihlolwe ngokugcwele, futhi ikhwalithi yazo nokusebenza kwazo kufanele ziqinisekiswe ngokuhlolwa kanye nokuhlolwa kwangempela ukuqinisekisa ukuthi imikhiqizo efanelekile ye-RDP ikhethiwe.
