3. Indlela yokukhetha: Yenza izinqumo ezisheshayo ngokusekelwe “ekubalulekeni”.
Ungaqala ngokubona izinkomba ezi-1-2 ozikhathalelayo, bese ulinganisela ezinye izinkomba ngaphakathi kobubanzi obamukelekayo.
Ukuze i-PU ingagugi + inciphise umzamo wokugingqika (umhlaba oqinile/ngaphandle/ibanga elide): Inayiloni iyathandwa; uma kudingeka ukuthula futhi kube lula phansi, i-PU iyathandwa.
Ukuze kusebenze buthule + ukuvikela phansi (izibhedlela/izikhumulo zezindiza/izitolo ezinkulu/izakhiwo zamahhovisi): I-PU iyathandwa; irabha ingacatshangelwa uma kudingeka ukumuncwa okunamandla kokushaqeka.
Uma ucabangela umthamo womthwalo + isikhathi sokuphila esiphelele (ukuphathwa okunzima njalo): beka phambili i-PU esezingeni eliphezulu (enobunzima/ububanzi/ukuthwala okufanele); ezitezi eziqinile, cabanga ngezakhiwo ze-nylon noma ze-PU ezisindayo.
Inhlabathi ivame ukushiya amabala amnyama: kuyanconywa ukukhetha ifomula ethi “irabha ye-PU/engaphawuli”, bese ulawula ubulukhuni bendawo yesondo kanye nokuhlanzwa nokugcinwa kwayo.
4. Iziphakamiso ezi-6 ezisebenzayo zokuthuthukisa ukumelana nokuguguleka kanye nesikhathi sokuphila (okubaluleke kakhulu kunokukhethwa kwezinto)
Ukukhetha okusekelwe kumthwalo oguqukayo: Umthwalo ozinzile owanele akusho ukuthi umthwalo oguqukayo owanele. Ukuze kuphathwe imvamisa ephezulu, kunconywa ukuthi kushiywe umkhawulo womthwalo oguqukayo ongu-20% kuya ku-30%.
Ububanzi nobubanzi besondo obufanele: Uma ububanzi besondo bukhulu, kungcono ukuwela izithiyo kanye nokumelana okuphansi; uma ububanzi besondo bubanzi, ingcindezi yeyunithi iyancipha, okuholela ekumelaneni nokuguguleka okungcono kanye nokuzinza.
Ama-bearings abaluleke njengezivalo: ngenkathi ubuso besondo bungagugi, uma amanzi nothuli kungena ku-bearings, "kuzoqina kakhulu uma kusetshenziswa", okulingana nokuthatha umhlalaphansi ngaphambi kwesikhathi.
Gwema umthwalo nokushaya okungalingani isikhathi eside: Ukujika okunzima endaweni kanye nokushayisana njalo nemingcele kungasheshisa ukudabuka kobuso besondo kanye nokuguquka kwe-bracket.
Ukulungiswa komhlabathi: Ama-chip esihlabathi/ensimbi “ayizinto ezisheshisa ukuguguleka kwamasondo”. Ukuhlanza njalo iziteshi kanye nezinto ezibambekayo ebusweni bamasondo kungathinta kakhulu isikhathi sokuphila.
Ukubhuleka nokupaka okulungile: Uma upaka endaweni ethambekele, kunconywa ukusebenzisa amabhuleki amabili noma ukukhiya okuqondiswe ohlangothini; uma upaka isikhathi eside, gwema ukuguquguquka kwamasondo ngenxa yokucindezela (imilenze/amabhlogo okusekela angasetshenziswa).
5. Isiphetho: Yisiphi Esihlala Isikhathi Eside Kakhulu? Nansi Impendulo Eqinisekile
Uma siqhathanisa kuphela "ukumelana nokuguguleka okumsulwa" (ikakhulukazi ezindaweni ezimagebhugebhu nasezimweni lapho umsindo ungeyona inkinga), inayiloni ivame ukuqina kakhulu; nokho, ezimweni zokusebenza ezibanzi kakhulu, i-polyurethane ibonisa ukusebenza okulinganiselayo maqondana nokumelana nokuguguleka, amandla okuthwala umthwalo, ukunciphisa umsindo, ukuvikela phansi, kanye nokumelana nokudabuka, okwenza kube ukukhetha okuvame kakhulu njengenketho "yokumelana nokuguguleka okuvamile". Irabha, enokwakheka okufanele, nayo isebenza kahle maqondana nokumelana nokuguguleka, kodwa izinzuzo zayo zithambekele kakhulu ekumuncweni kokushaqeka, ukunciphisa umsindo, kanye nokuvikela phansi.
Kunconywa ukuthi ekugcineni usekele isinqumo sakho ezimweni zakho zokusebenza zangempela (umhlabathi, umthwalo, ukungcola komswakama/uwoyela, kanye nokuvama kokusunduza). Uma kudingeka, yenza izivivinyo zokuqhathanisa usebenzisa amasampula, njengoba ukukhetha imodeli efanele ngokusekelwe kudatha kuzonikeza ukuzinza okukhulu.
Okunamathiselwe: Uhlu Lolwazi Lokukhetha Lwabahlinzeki/Amafektri (Uma luphelele kakhulu, kungcono ukufanisa amasondo)
Isisindo semishini iyonke/ukusatshalaliswa kwesondo elilodwa (kungakhathaliseki ukuthi kukhona ukulayisha okungalingani) kanye nesidingo somthwalo oguquguqukayo Uhlobo lomhlabathi (i-epoxy/PVC/ithayela/isimende/i-asphalt, njll.) nokuthi ngabe kukhona yini imiphetho, izikhala, ama-ramp Imvamisa yokusetshenziswa (inani lokusunduza/ibanga ngosuku) kanye nesivinini Indawo (ukuwasha okumanzi, amabala kawoyela, izihlanzi zamakhemikhali, ububanzi bokushisa) Indlela yokufaka (induku yophahla/isikulufu/induku yokufaka) kanye nemikhawulo yesikhala/ukuphakama kokufakwa Kungakhathaliseki ukuthi ibhulakhethi yensimbi engagqwali ethule, engenamkhondo, elwa nokuma, ibhulakhethi yensimbi engagqwali, ukukhiya kwebhuleki/isiqondiso okukabili, njll. kuyadingeka.
